That is really cool. Nice find!

That was fun, thanks

I have a Fender super reissue, when I turn the reverb up past two, the amp distorts and loses volume. Can you share any ideas what may cause that? I put all new JJ tubes in it and it didn’t fix the problem. I’m afraid to use it for a job, fearing it might burn something up. It’s around a 92 or 94

What if you just want to take the original shell but make the internals a solely a Bluetooth MP3?

Lot of that stuff could be just put into the nearest dumpster

You're in the Dog house!

I think the auction added a whole lot of fun to that event. Thanks for the video.

Nice to see you two buying a bunch.....thanks for the video....

I loved that Mohawk RX . . . congrats on the purchase . . .

Not a bad swap at all.

Terry, you made me being a ham after watching your guitar amp vids. So, yes, my fav channel. 73 de db3mi, bemi

Well done, Terry! I've had to replace similar components under similar conditions, and you point out the proper technique. You do have to learn how to look and understand how the components mount, and vary your methods accordingly. The right tools help as well; a temperature controlled soldering iron, quality desoldering wick, and diagonal cutting pliers as you showed.

How are you reading a voltage on an out-of-circuit transistor? Checking for a short, I take resistance readings in “ohms” .

Not knowing the reason you were changing this out do you still have this part to measure the individual caps for capacitance, ESR in respect to the individual Lelon and Nichicon parts? That would be interesting to know and/or is there is a datecode on the Weber can to get a rough MTBF of the Weber construction and the datecodes if marked on the individual caps?

Terry, Great idea of keeping the original cap in place..and adding the jack to the chassis. I still have my original 1481..all original except for grounded power plug…and I replaced the first tube to the left..the original is still in working order it causing some minor issues. I also have a vintage Fender Champ ..same vintage ..I think the Silvertone outshines the Champ in a few areas , you mentioned the Silvertone tubes..I was told my a few sources that Sears used RCA tubes that they rebranded..I play my 1482 with my all original Sears Dolphin head 415 U1 copper guitar Great site you have here!

Cool, cool. Decently affordable, but we both know the big bucks is spent on irons for tube amps 😂

My childhood dream toy...

650 Volts + Wine.. ...well, what could be wrong? ;)

0:27 same problem on my 40c

I couldn't really hear it on the video, but after putting it into my Deluxe circuit...WOW! Huge difference...nice smooth mids! Thanks for this! Bought a cheap pot on Amazon, and now waiting for an Alpha to get here. Not sure I want to do the final mod after a glass of pinot, but maybe do the mod first...just sayin'. 🙂

The wrong ohm setting probably blew the tubes to begin with

I wouldn’t be surprised if this guy had the skills to build his own amp.

Pitiful

An amp with a 6AQ5 sounds like a Marshall.....Loved mine.

Nice looking amps ❤❤

It's interesting that the 6AQ5 began to flatten the bottom of the wave before going into grid clipping. The 6V6 clipped both sides simultaneously. I'm sure this is due to the bias point being more center biased in the 6V6 amp.

Terry, Please make a video of the inside of these super kewl amplifiers!

Both of those amps are fabulous Terry. Kudos.

good job Larry!!

I just converted a Sidekick 15, significantly more challenging due to small size. Added negative feedback, tonestack cut. Impedance selector on rear. And added mid pot to champ circuit

My friends had one go DC and destroy four JBL 12" PA drivers.

I miss my 400, should not have sold it….

The only made a few of these, you are lucky to have one.

Your boards are awesome. I have used them to convert SS amps to tubes for friends.

The kid is hot tonite. So fitting for a start up.

can this use 6v6 power tubes and 2x 12ax7 ?

Great project i just wish we had more AM stations. I had several 6 meter AM stations tjat i have mpthballed because no one to talk to KA5WZY

I just read somewhere that one has to be careful sometimes if one side of the speaker out is grounded or also can create problems. They suggested first ohming out (with all turned off) the two speaker leads to chassis ground? Also how do you check if signal generator is not grounded?

For those outside the US, the older machine screw system is common even today and most vintage American amplifiers use it. The first number is an arbitrary rod size and the second, the number of threads per inch. Very common are 8-32, 6-32, and 4-40... also 10-32, 10-24. This maybe useful in locating replacements.

Maybe the assembly person ringed the wire with their strippers back in the day, and it took 40 years to snap. I could see how this could happen, having worked in a factory panel shop doing point to point wiring.

Great video H.H. when I was 10 years old or so, my Dad gave me a clapped out S-40A and a check book register as a log book. I'm 61 now but, I paid $30 for an S-40A at a hamfest. I love listening around on it. Take care & 73's. - AA0QZ

Is the fishing line twisted pair, so you can provide the proper filament voltage? Do you have any problems with the lures and the "current flow"? 😊

Great Video Terry! My goto filter caps are CE Manufacturing and F&T. Always have had good luck, performance, and long life out of them both. Cheers 🥂

Only one thing more I wouldve Done. I noticed a couple of bumble bees in there that I wouldve went ahead and swapped out because they were notorious even when new for cracking and shorting. Im an 80 year old RETIRED Tech that started out taking electronics as a Vocational course when I was in high school then went into mechanics after I got out of the army but went back to electronics after I retired and now build and repair computers as a Hobby

It’s too bad. People just don’t know how to package things. I bought a hewlett Packard Barney Oliver amplifier a few weeks ago from a guy. Gave him very specific instructions on how to package it, which he didn’t do. I don’t even know where he found such a thin box. Box came destroyed but thankfully the unit made it. Could have been a lot worse. UPS store is just staffed by college age kids with no experience in shipping/packaging, I’d never use that service.

Wow! I purchased a used JCM Marshall 4501 combo from Guitar center. I received it yesterday from UPS. Plugged the amp power cord in and made sure the gain and volume knobs were all turned down. I turned on the amp w/ out the guitar plugged in and after less than a minute it started making the same exact popping noise as the amp you are demoing. It started getting louder. I plugged in my guitar and played some chords but no sound came out from the guitar except for the popping noise that was already popping. CRAZY.... any help would be greatly appreciated. Thanks

Just made this thing. Haven't built or soldered anything in 20 years and it just works. Was quite fun! Now... time to fix my Fender Bassman! Thank you Terry!

Brings back memories... The first time I got zapped by plate voltage at about age 8 or 9, I was troubleshooting a Heathkit AA-100 amp, using the brilliant technique of finger signal injection. I was working my way through the stages, hitting the grids and hearing the speaker. I got to the output tubes and somehow miscounted the pins and poked the plate. I saw a big blue flash inside my eyes and was ejected back into my bed from where I was standing. Good lesson for a kid 😂 ☮️
