Wow, not only an electronics genius, but Mark also plays guitar 👍👍👍

Just what every electronics workshop needs, a test strat.

Watching People actually manefacturing stuff instead of buying or outsourcing is awsome!!!! please more!!!!

Is there no end to your talent. I’m very impressed with your efforts on this one Mark.

Before this channel, you couldn't easily find it all together in one person: knowledge, charisma and sensibility. Mr Mark, you're all of those things, your channel is one of the best here and I look forward for more from you, sir. Well done!

Etching your own board, finding a functioning chip replacement. You're a beast Mark , thank you! I've been watching your videos for the last several evenings

“Better discharge the static…Not that there is any in this country” 😅

I can build and troubleshoot electronics, and I have a lot of fun with it. However I can testify that Mark is on a completely other level. Great to witness this proficiency. I am also impressed with the cheerful easygoing attitude. Cheers Mark

That’s why I loved fault finding as nothing quite replaces that buzz you get when you switch something on after a repair and it works ! It takes a certain type of person to be a technician. It’s addictive lol. The more complicated the repair the bigger the buzz. At nearly 70 I can’t do delicate work anymore due to trembling hands and it’s so annoying, but I still have all the test gear !

Never seen handmade pcb's before - I've just been educated AND entertained! Thanks man, you're a modern day McGyver!!

Glad you liked the T strippers! Ideal entered the market with abrasives for DC armature maintenance and branched out. Glad you got some nice sounds out of the Mistress.

It’s always a great day when Mend it Mark uploads a new video. Thank you!

The fake chip has marks on top showing the original top surface was ground off. The half moon indicating pin 1 is also shallower than normal. Amazing effort rolling wire to make flat pins!

That really took me back to my CDT lessons, I loved making printed circuit boards like that 😊

Hi Mark, as a fellow engineer from Walsall I just wanted to thank you for the enlightening videos ,keep up the good work, every day is a school day 😆👍

Any machine you don't have?.... lol Thank you Mark for letting us walk along with you on these projects. Sorry about the fake chips. Really enjoy watching you work your magic. Thank you from the US!

I used to work in a small music store in the 90s, and I had to deal with very similar repairs as this one. To be honest, I would have just hard wired the different chip with jump leads. Crude, but effective. I like your way better.

Wow solid work! 😀 Lovely bringing a device like this back!

The counterfeit market makes things super frustrating! I loved that you made your own PCB for the replacement.

As usual - very clever and resourceful repair. I think I might have added a power light as a bonus.

... and you're a muso as well! I'm more impressed every day Mark 😆 Possibly the most impressive tech repair channel ever mate, love your work!!

Jasus! As always an amazing repair and engineering work Mark. First time I’ve seen you play, no end to your talents. You’ve opened up a big can here Mark with your work around. You’ll be bombarded, I’d like to jump in first, will you make me one of those boards for my HH Clockwork Concubine, I’m on my last 1024A Might try buy some 512s as spare. Keep up the brilliant work. Thank you Trev

That old peddle has a nice warm sound to it. Your nice little modification board was the most interesting bit of that process. Nice work. You have a lovely workshop, it would be interesting to do a little mini- tour of it in a video one day. BTW - I love your guitar, lovely colour.

Im so glad i found this channel. Please more of these. So cool.

Brilliant! Love watching your repairs - its the chuckle that's the icing on the cake!

to align all the legs before soldering them you can use a spare socket and press the legs into the spare socket and then solder all the pins at the same time.

Подумал - Сашка Лаэртский, ан нет. Но когда в конце заиграл на гитаре - засомневался ) Спасибо, вы очень крутой спец!

watching you work your magic, i regret not getting into electronics when i wanted to, as a young electrician apprentice. Now im just a sparky, but playing at fixing amps as a hobby, learning from you at nearly 50. Thanks Mark

It's fascinating to watch you repair things, thanks for your videos !

What an absolute pleasure to watch somebody who actually knows what they’re doing 😎 Shame you’re maxed out with work, Mark - I’d love to send my old EHX Deluxe Memory Man in…

Fantastic repair - top notch work as always. So glad I found this channel. Keep up the great work!

Chip straighteners? Who knew? That was really interesting Mark,even though a lot of it was over my head🙄Nice Strat BTW

Love your craftsmanship and cheerfulness!

It's fascinating to watch you repair things. Thank you for sharing such a entertaining video.

Always in awe of your capabilities and skill Mark. Outstanding work as always.

The SAD1024 is virtually unobtainium. They sound great for guitar, though. I've made a pop-in replacement using more modern chips, as have others.

I've watched many of your videos Mark .. and there's always another bit of kit! Wire roller ... chip straightener - awesome

You've just got yourself another subscriber. Very informative and interesting video. Gonna binge watch the rest of your content. Nice work.

Multi talented, very impressive. Thanks for the great videos Mark. Keep 'em coming.

Amazing to see you at work there Mark and we are all in awe of your broad skills re electronic manufacturing and testing.

What an amazing fix. Found your channel recently and am loving it. Real hardcore techie stuff.

Your process for making these videos is spot on. I can't tell you how much I enjoy your work, Mark. The breadth of gear you cover is awesome I can honestly see you going a long way!

Omg, nice guitar! This was a fun episode.

You are a pretty incredible dude. You've reignited my love of electronics, that is, the knowledge of each component, identifying circuits. Keep up the good work.

Respect, this brought me back some solid memories of lessons creating boards using nasty chemicals, awesome!

Mark, Thank-you for your response on your Cats name! I just started watching your video's and now I can't stop! So interresting. I have those wire strippers myself, Their awsome! I live in the United States, In a small town in Northwest Ohio Called Maumee. So your vids reach far and wide! Keep up the great work! Mike Z.

Amazing work, a lot of different skill sets there. Nice Work Mark !!

Thanks Mark for the expert troubleshooting and repair lesson! ☺🙏

Once again, a most enjoyable video Chris

Fantastic work Mark, keep the vids coming 👍

Very nice work as always! I didn't know you played a little Guitar! Enjoyed this video as always and thanks for sharing!

Who would know that one of the most involved repairs I've seen you done would be of such a simple circuit! Always a pleasure to watch your vids Mark

Great repair Mark. I learned a lot from your channel so far. Keep up the good work 👌

Fantastic repair as always, very skilful, I love the way you never give up, I thought that would have been a gonner, but you did the business, well done.

Your approach is spot-on. Top-notch work, Mark. I guess I’m gonna get that mechanical workshop going after all :)

Always enjoy to watch Mark working, so good working methods, cool tricks.

Excellent Mark. Just found your channel and amazing work mate.

Hi , I just want to say how much I enjoy watching , you are brilliant at making the very technical repairs interesting and fun.

“Night after night, who treats you right?, Baby, it's the guitar man”. 🎸

I am impressed with your road to succes towards half a Mistress with satisfying result!

It's great to watch a genius at work. A man of many talents.

Amazing! Seems as some of your other subscribers had the same thoughts as I had like is there no end to your talents in repairing items but also being able to play the guitar. Really enjoy watching your videos - great stuff 👍🏻👍🏻👍🏻👍🏻👍🏻

Awesome fix Mark - great improvisation.

Good repair Mark and nice guitar playing at the end.

Awesome work mate, really enjoying your show. Cheers.

loved it all and the guitar solo, excellent stuff mark thanks

From start to finish a brilliant video and your tooling is nuts!

Is there no end to this man's talents ...........................................

I know that feeling when you plan and prepare everything, but at the first switch - things don't go to plan... Kudos for sticking with it and working out the solution!

Amazing Mark, you really excelled this time. And You play Guitar too, no end to your talents. Keep 'Em Coming.

Really enjoyed watching this. Great post.

Great job, well and thoroughly done😮

This absolutely made my morning, thanks Mate!

Man I did not predict that a home made circuit board would be part of the fix! That’s truly next level stuff! I’m sure you have no shortage of things to work on but the guitar community are predicting a huge drop off in the number of people capable of repairing tube amplifiers in the next few years. Would you consider making some content tackling common issues associated with guitar tube amps?

really enjoyed that episode. Thanks!

Thanks, Mark. I love your presentation style and excellent production qualities. Cheers!

Awesome work Mark, brilliant fix.

TOP shelf, mate. You've got skills!

Another great video, Mark. Definitely a lesson learnt about fake chips - and not a bad guitarist, either.

Very very impressive repair Mark, simply fascinating skills.

Very nice Mark. Enjoyed the repair.

Greetings from Germany! I like your nice way of explaining electronics. It`s calming to watch you! Keep it up!😀

my main interest in electronics is audio..guitars, pedals amps, mics, preamps, mixers..love these ones

Great content and advice… Cheers Mark!

Awesome as always... Really enjoyed this one thankyou

This is SUPERB video. Thanks for sharing it.

Love to read those schematics with you. Takes me back, very very satisfying.

Nice guitar-playing, Mark. And nice fix too.

Excellent video!! I enjoyed the guitar playing as well!

Love your work Mark and so well explained

Thank you Mark, another great vid.

Great vid Mark! I love your innovation!

A man of many talents, well done

Ahhh Mark, I have to go to bed ffs! Oh well. 30 minutes less sleep can't hurt.

Great work, Mark. got the same pair of strippers in my college electronics kit and they stayed quite sharp for around 12 years.

Hi Mark... Nice fix, most inventive! I've been using a T Stripper for about 15 years now. Still as good as when it was new. It cost about a tenner at RS Components. A lot of money then but it was bought for me for doing a small fixing job on some amp or other. Cheers.

A great repair again, Mark! Thanks for the video, I enjoyed it.grz

Really enjoyed the design and build of a “custom” chip👀 superb.

Thanks, Mark. You are an excellent Engineer

11:12 Thanks for the great tip of floating the non-drilled single sided PCB on the etchant!
