You are a much-needed role model for young girls. No longer are electronics repair the domain of we elderly, gray-haired males. Love watching you work; I marvel at your knowledge of old amps.

I found this video very "soothing" as well as educational after a shitty day at work!

Smashing job on this amp. The best part about this is including a demo by the owner. No one does that. Brilliant! - Mike from Black Cat Amplification (Baltimore, MD)

Hello from Northern Cali!! After watching your “1/4” speaker jack replacement” and “Draining your filter caps” videos I decided to repair my 1978 Silverface Champ myself. I successfully replaced my fuse link, installed a new Jensen speaker, and retolexed the top and bottom of the cab with red sparkle vinyl. I had never heard the amp in the ten years since it was gifted to me! It sounds incredible! I’m sure it could stand to have those old worn caps and resistors replaced and I now have the confidence to attempt the job myself. Thank you for the comprehensive and encouraging videos! Keep up the excellent work, Colleen!!

I learned basic DC and AC electronics when i was around 11 years old then learned RF and digital electronics. This was my hobby as a child. So I highly respect what you are doing. It amazes me that someone your age today has this knowledge. It's a very rare set of skills and knowledge you have today.

Nicely done! I think your videos fill a niche that others don't. You show clearly things like the layout, wiring (well explained) actual soldering work, component function/purpose, and more. This is super valuable for those just learning about amp work and what's often lacking in other amp tech videos. Showing the bias calculation steps (Rob's calculator! ) also great! Thanks and looking forward to future posts as well.

Oh snap! Look at this! Uncle Doug would be glad to see someone from the younger generation taking up this lost art. I know I am! Keep up the great work!

I really enjoy watching you restore these wonderful amps. You are an excellent Diagnostician and Technician. As a musician who's played for over 50 years, it's a pleasure watching you do your work. 😁 👍

My first amp was an early 70's Champ. It is great to have found your channel..

Solid! Commenters are right on the biasing. I tend to replace champ filter caps with a 4 node 40-20-20-20 in case they want to use the other version power supply. 40 is technically too high for a 5Y3 but who really cares. The other main mod worth doing is converting the tube filament winding to parallel from series.. especially on speaker changes. Helps cut out the hum. Great video! Keep them coming!

Thank you for all the nice videos. I gave my son a 1974 Champ. These amplifiers are amazing.

Great job, well done! Just two wee tips from my side: Those late 70s cheapy Fenders often have one massive construction failure, that Fender probably came up with to lower production costs: Instead of running twisted leads to the filaments of the tubes and balancing the center either via grounding a centertap of this winding or by adding two resistors (usually 2x 100 ohms @ the pilot lamp), the changed to running one side of the filaments via the chassis - which was a VERY bad idea... This should be modded back to twisted wires, which will result in a significant noise reduction! I did this mod with my 79 Musicmaster Bass amp - and it was a MASSIVE improvement! Also, I would solder the filtercap directly to the chassis, to prevent it from starting to rattle in the future. Check out Mr Carlsons soldering tips - he uses a modded soldering-gun for this purpose - works great! For biasing cathode biased amps, a "Resistor decade" (don't know, if this is the proper word - we call it Widerstandsdekade here in Germany) can be very handy - so you can dial in the resistor values, until you'll find the perfect bias, then replace the item with a proper resistor, and you're done!

So nice to watch you, a young woman who not only has knowledge of electronics and such but is even interested in this to begin with......so Awesome. I'm an old geezer who plays several instruments and this takes me back to a time around 73 - 74 when I would plug in my 67 Gibson SG Jr. into my 74 Fender Champ. You can imagine the sound that single plastic P- 90 pickup strapped in a plank of deep burgundy mahogany in my Champ cranked up to 10......oh HELL YEAH! I know you Guitar player's out there can tell this Deadly combination is nothing short of a ROCK MONSTER, lol.....anyways love this video.....🎸🎸🎸♥️

Thats what an amp should sound like. The clean tones are just whooaa! Great job as usual Fazio!

I just discovered you. I know nothing, zilch, nada about amps. You are mesmerizing. Just watching you work. I'm 72 and before I head to Jimi's abode, I'm going to build an amp! Thank you!❤

I love that you are into this hobby and do it very well. Congrats to see someone young like you so knowledgable.... You go girl !!

I just stop by, to check out on the video and I was mesmerized by it. This young woman is really a pro on what she does. I become a subscriber in a heart beat. Thank you

I'm very impressed. I like your "slower pace" and relaxing delivery of your knowledge and explanation. Very meticulous and neat work. Thank you!

One of the clearest explanations on the internet of anything technical, let alone amp-related. Keep up the good work! It's so satisfying to see someone know exactly what they're doing.

Your videos are excellent. The work you do is so tidy and logical.

Ah, my first amp, and my favourite. Bought it 2nd hand in 1978, never forgot how good it sounds, as per your customer's demo! Thanks for the memories :)

Those Champs are the Best Buy for the money . I’m in awe of your knowledge .

Very nice. I had a Champ at least the same age that I modded - blasphemy I know - but no electronic modifications. I put in a heavier 10" speaker. I did have to enlarge the baffle opening as well as carve out a bit more space for the flange of the speaker but I had tested it first and it was definitely the sound I wanted for clean jazz and a browner rock sound with a pedal. I still own an Ampeg Gemini VI (head put in its own cabinet) that is spectacular. It's got the tremolo, reverb pan and an accordion input! Someone should have cloned that amp. Enjoyed the repair and I'll check out others. Cheers!

You are a very technician. Thank you.

They used those Princeton power transformers back then which had too high of a plate voltage tap. Fender didn't care - they did it anyway. That is why you had to go so drastic on the resistor value to cut the current. It is the current gong through that matters, not so much the voltage. I refurbished a friend's early seventies Twin Reverb. Shortly after that he had to go into surgery to have half of a lung removed - lung cancer. As a gift for doing the repair he gave me a full-up chassis from an early seventies Champ. Well, I took that chassis and modded it to the late fifties version - the tweed version. Then I took some maple from a tree that had been cut down locally and made book-matched sides for the cabinet I made. I painted and stained using an airbrush the Fender three color sunburst with the top and bottom pieces black and of course black around the perimeter of the sides with the sunburst red rim and yellow center. I threw a new Jensen ceramic magnet 10" speaker in there, but before I put it in I broke it in with a 60 Hz signal for many hours - had to leave the house for a while. I used some softener on the suspension area of the cone. Without doing this the speaker was too bright, fizzy and harsh. This softened it considerably and made it warmer and easy on the ears. It had more low end than the typical alnico would. A 12" greenback sounds really good as well. My friend was recovering and it was bad. He had a very young daughter and a teenage daughter and his wife was putting in massive overtime to keep things moving. It was tough all the way around. I took that amp up there in the mountains to his place and gave it to him. It sounds stupid, but he was losing hope and faith and it was getting desperate for relief. He was able to put that little amp next to his recliner and play, which really made a difference. I don't really know why I did what I did with that amp. I wasn't even aware at the time how dark things were for him. He certainly wasn't aware I was doing it, and I did not even know what I would do with it when it was done - that is just how it played out. We can and should make differences in the lives of others - the take away. To this day many years later it has become his favorite amp. That might have nothing to do with the sound, although it sounded just like a tweed Champ should. I really had to tame that high voltage and the resulting current on the tweed version. It was the most frustrating part of the build. Later I built myself one from scratch and keep it laying around for those days when I need some low wattage inspiration. I never built a cabinet for it - I am such a lazy hack. I get shocks off of it to remind me - oh yeah, gotta get a cabinet built. It is still just a chassis. Thanks for the video. Good stuff!

A little tip: use the drill's clutch feature when putting those screws back in so they don't get gnarled. Keep rocking, sister!

Girl you ARE a silver faced champ! :p Love your work and videos ! Thanks for sharing

By sheer dumb luck, my first tube amp was the very early 1963 Fender Blackface Vibro Champ. I got that amp in the very early 80's for next to nothing and wish I had it today. I plugged my brand new Rickenbacker 360 WB 6 string into the Vibro Champ and that's when the lights went on about the tube tone! A big step up from solid state tone!

Great restoration to stock! Thanks for including the before and after clips. It's a thing so rarely done, and yet so important to hear.

I just wanted to say Thank you for sharing! It is so interesting how you diagnose and bring back to life vintage amps! When I watch you work, I understand more and more about electronics. You really inspire and encourage people! Thank You!!!

Bless your kind heart for sharing your wisdom with us:)

HINT - Use your multi meter set to Current or an Analog Ammeter in your ground jumper to measure Bias current directly. Great Job, you do Good Work.

I could watch amp restoration videos all day long. Great job!

Stumbled across your channel by accident and it was a lucky get. Retired electronic/tech/engineer with 38 years experience. Also a guitarist. I still have the first amp my dad bought me. 64 Fender Princeton that I will be restoring. Excellent videos. I was watching this video and just wanted to comment on the part installing the multi cap in the chassis. The choice of not grounding to the chassis. That chassis is s huge heat sink. Lol. We had an iron we called the solder bat for things like that. This is great. I subscribed. Thanks!!!!!

Thanks so much for the knowledge you're passing on... I feel you are demystifying tube amps and its awesome

Thanks for the video. I'm going to make a cap voltage discharge tool so I can get inside of my Music Man 65 and tighten up some pots and take a look around. In an industry that's been so dominated by guys, it's hard not to sound patronizing when I say you are an inspiration.

I learn a lot from all these videos. I am not a repair man by profession but I enjoy messing with things. Thank you for all the knowledge.

A 1979 version was my first amp in 1980. Started on fire as it got so hot the solder melted and ...... Lucky "Basic Bob" lived across the hall and had it running in 10 minutes. 40+ years later I want to make one.

Your appreciation for respecting original designer and yes thanks for showing all steps involved. As time goes on you will become a true Luther of Amps and I'd assume you are dialed in to the movements of the axe role.

Amps are best left stock; pedals can boost and add effects. I've got a Fender bassbreaker 007 ltd that has gain control, treble boost and two 12ax7s and a 6bq5 for 7 watts with a 10 inch greenback that has the crunch you demonstrated in the beginning of the video, keep on doing the great 👍😃 work 👏👌🔊🎸

You do nice work! The only thing I would change would be to make the cathode bypass capacitor a 50 volt part, since you now have 32 volts across it and it needs to be derated further because the 6V6GT is underneath, cooking it. For the electrolytic tabs, I have a beastly 450 watt weller gun! Nothing like a fire-breathing dragon for those tough jobs! 💪 You have tremendous expertise! Keep on truckin'!

I'm really impressed by your attention to detail! The future of valve (toob) amps is safe in your hands!

Hey! Great job, very thorough. I did notice that the Warehouse is an 8ohm speaker, but the Champ calls for a 4ohm (I think!)

Amazing!! A fan of this person. Her interest and dedication to what she does is a breathe of fresh. Wondering who or what inspired her in this field😊. Thnk you!👍

Great work and nice playing from Taylor.

I like how you explain the function of various components in the circuit......how nice it is to know those things.

Wow!!! What a huge difference!!!

Wow.. great lady... cheers ma'am

Hi found this by accident when could sleep tonight ... wow great stream and awesome job showing/telling changes you expect to do to restore back! Love it Good job young lady keep on preserving amps !

I have this exact amp. It's so addictive to play on. I'm always blown away how an old school bedroom amp has stood to amps far above it's price range, for decades. Love your channel. I've worked in low voltage for the last twenty years and really want to build my own amp. I've been building transformers and fly back coils for the last year, or. I need to get back to work. Channels like yours are inspiration. Thanks!

Respect. You made a messed up old amp sound like a true champ.

Thanks for the calculator link. Very handy. Nice work on the amp. There is competency galore around your work.

How could someone know so much about old electronics. I'm impressed.

I love that the young folks are doing this keep this trade alive as long we can

way to bring back that Champ! Keep at it!

Thank you for restauring this wonderfull lil' amp to its original state - I have one from the same year and it doesn't need any mod at all!

Nice When you were installing the two jacks, I was thinking please don't use pliers.... and you didn't. Proper nut driver Professional. You are a special young Lady. You have my respect.

I remember when I was 7 years old and took apart a phonograph player which had tube almplifiers. At 7 you don't really know what you are doing, but one of the tubes was leaning a little and as the chassis was powered and I was listening to a 23 rpm record, I grabbed the tubed to straighten it out and then; zap! I got a very good jolt of power. I then respected electricity.

When I have amp issues you will definately be my go to!! Keep up the good work!!

Thoroughly enjoyed this video and will now make my way through your other projects. What I particularly liked was the pace of delivery plus the on-screen notes about the function and impact of certain components (and the impact of changing the component value on the sound) on the circuit, and the way you highlight the section you’re speaking about on the schematic and layouts. I feel functionally dyslexic when it comes to understanding schematics etc, and this helps immensely. Thank you.

Nice job, compliments on taking the time to remove the old solder with your solder vac. Makes a cleaner, more reliable connection.

WOW. Your channel is so great! Greetings from Poland.

This is how you do an instructional video! Great camera shots and lighting; clear, concise descriptions of what you are doing and why; and I really like the supplemental notes added in screen. Subbed!

Nice clean Build. Love looking at schematics. Felt good to see it cleaned up and put back to stock. Thanks Fazio Electric! Much Love, "The Shire".

Excellent presentation style. Rushing around inside a chassis is a bad idea and I dig your relaxed, yet to the point attitude. Liked & subscribed - and a reminder I need to give my old '65 VC a service! (and nice to see no misogyny in the comments section too, long may that continue!)

Colleen, Another great video with everything explained in detail you're the best in my humble opinion Ed

Great job. I tried for the first time the other day to change the electrolytics on my 66 deluxe reverb cct board, and found it quite difficult, you make it look so easy. I manged to do the single, but couldnt get the doubles in. lol Will try again when i get the time and have calmed down. Thanks for the tutorials.

It’s good to see your channel taking off. Your following growing every episode. Thanks for your hard work.

Good video! The 70% dissipation rule doesn't normally apply to single-ended amps, so for a single 6V6 you can bias more around 90% at idle.

I feel so old because I did this stuff so long ago but wtf, it's nice to see people still learning from it! I mean that in respect because it isn't as easy as people think.

Good job ! In Single Ended, 100% for plate dissipation is good, no problem. 75% is for PP.

And this video got me to become a patron...looking forward to more. Glad to see a new generation doing this work. Keep it up and thanks!

Great job, amp sounds killer! My first amp when I was 13 was a 1965 Blackface Vibro Champ. There was no distortion pedals back then so I use to put it in the closet with a bunch of pillows and crank it up. Then the 'Maestro Fuzz Tone' came out and I could take the amp out of the closet and play it without driving my parents nuts.

That guy Taylor was pretty good! Awesome work. Sounds much better.

Great amp restoration and love the clear explanations of the things you were doing! The resulting amp sounds fantastic!!!

Fazio, . . . . . You're Good! . . . . . . DAMN GOOD!

It's very satisfying to undo strange mods/poor repairs. Love the camerawork

You converted it from a Fender Cramp back to a Fender Champ! Nicely done love it.

Rockn rolly,electric Lady 👍🎸🎶🧲🔩

Very nice job and you explain everything really well. If I may suggest, get a really powerful iron or gun for chassis work. That very large change in the output cathode resistor might indicate that there's some leakage somewhere. Or to be specific, if the DC blocking cap to the output tube is leaky then that will lift the grid above ground and that will lead to higher bias with the stock cathode resistor.

Nice job. It's great to see a young person working in electronics. Most of the techs I know are over 60 years old.

Very well presented video, thank you. I hope you don’t mind a suggestion, but if you put your drill driver on slow speed it you will bounce less on the screw heads as they are being run in. I use a super slow old black and screw driver that works well. The owner looks happy, and I bet Leo’s ghost is resting easier

You do good work. A lot of gain stages and masters volumes were added... I’m thinking around the time Mesa Boogie’s came out. Trying to remember the exact timeline is hard now. You know... after the eighties! Ha ha! I remember going in to repair shops and seeing the techs doing these mods often for people. These years of Fender amps weren’t getting much Love until more recently. Funny how our ideas change about such things after time. I mean... now... copies of Fender products from that era, made by Fender go for a lot of money. Lol. Well... by my standards anyway... Again... nice job... and... Thank you for the video!

Nice job of restoring amp from Frankenstein land. With cathode bias, 100% of maximum dissipation should be your goal. (Verified on Robinette’s page). That cathode resistor should be 470 ohms so something is screwy with the tube. The plate voltage shows as 350 on the schematic, so your 385 +/- is in the right ballpark. Checking bias and tweaking is a great idea, but if you have to double the size of the cathode resistor something ain’t right. Part of the noise issues could be the heaters. Fender used a shortcut and simply grounded one side of the heater winding on the PT. Sometimes re-wiring the heaters with a virtual center tap reduces noise, especially on a single-ended amp.

I use the same calculator. It sure makes life easier. Thanks for the great videos.

This is wizardry. So cool.

Watching you flow solder is so satisfying.

Not every day we see such a qualified and knowledgeable amp tech who happens to be a young lady. Outstanding, and great explanation as to each step, the "why" for changing out resisters to capture proper performance. You're the only tech I've heard mention 75% plate dissipation...most of your colleagues shoot for 70%. That's fine by me, you're quite talented.

Thanks for sharing! Long live Fender ☝🏻

I had my Champ stolen. It was a really good one from around 72. It was the best one I've heard outside of an old friend's Vibro Champ that turned out to be malfunctioning, in a spectacular way. When he got it "refurbished" it ruined the amp's magic. That was an exceedingly rare, freak occurrence, so everyone, don't hesitate to get your amps maintained.

if my gear were reconditioned this beautifully, my tears would surely drop every time I play it.

I really appreciate the education about guitar amps. Thanks for making these vids.

This is the best thing I’ve found on YT in many moons. You are awesome!

The mods might have been gritty, but this is a greatly improved tone. USEFUL in the studio!

Nice to see the amp put back from a hash job. Great videos D#

I really like the way you work

150 cable channels and nothing on so I watch amp rebuilds. And I love it! So glad I found Fabio Electric! You do such a great job! Dave Gries of Gries Amplifiers does an amazing job using the Blackface Champ as his base for building his Gries 5. It is my main gigging amp for low volume gigs. My favorite design along with the Deluxe Reverb.

Excellent job at showing how to use the layout document and schematic to put a modified amp back to stock!

I never opend any of my amps ,never have any intrest what so ever whats in there. Then you pop up on KZfaq and hocked me right up😀 You are so Good to explain ,and the camera is always perfect placed. All the best to you from Tommy in Sweden 👍

I swear you’re a genius !
