The Electric Mistress Repair

Mark repairs a 1979 vintage guitar effects unit, which features a super rare Bucket Brigade Delay chip - the Reticon SAD1024. It doesn't go well, and did Mark get scammed???? FAKE component alert!

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

I must admit I had a Bubbles moment there.

[@godsinbox]

soldering skills say this is no genius. also why does circuit say copyright ralf metzger, and nobody notices the breaches of IP.

[@xeroidkid]

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

[@roxxliveracing2039]

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

[@paulperry7091]

Just what every electronics workshop needs, a test strat.

[@mauriciobeligolioliveira]

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!

[@robburbrink8277]

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

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

[@peterhyams6824]

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 !

[@mohammedisaa9952]

@peterhyams6824 Just a thaught....... you could consider teaching a youngster who wants to learn, and he/she could be your hands? Im sure you could still get work if thats your profession, as mentoring someone is as though you continue your work through someone else, and eventually you could hand over your business to that person who would continue to provide help to your community 🙂 ?......

[@thrillynewt]

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

[@thrillynewt]

@monsieurtechnical it's not his fault anymore now, of course I fell down the classic youtube rabbit hole 😁

[@morph-the-cat]

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

[@kenp9073]

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!

[@tbonky]

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.

[@tim0steele]

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!

[@paulmichaelfreedman8334]

Not as consistent but an iron strip and a hammer will also do the trick. But Mark's way is more elegant and professional.

[@tim0steele]

@@paulmichaelfreedman8334 You could also use a socket with long pins

[@paulmichaelfreedman8334]

@@tim0steele I'd have just made them longer and soldered them into a vero board, them solder the pcb on the other side of the legs, and snip off the legs to the right length. But to each their own of course. Mark's skills are top notch.

[@pilier3]

Brilliant, I started 40yrs ago as a pcb process engineer, that was genius…

[@malrex0mari]

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

[@user-xv8yg1li2t]

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

[@fogbullit1000]

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 😆👍

[@rvmeushaw]

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

[@mohammedisaa9952]

A 12 volt led doesn't cost the eart, and a hole isnt that akward to drill with a "splodge" of glue 😂😅😂😅😂

[@phatwayne]

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

[@scottaumann]

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

[@DominicClifton]

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.

[@arlo0011]

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.

[@Fishfingersarnie]

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

[@anthonybarra2391]

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

[@plunder1956]

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.

[@marktubeie07]

... 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!!

[@joshfreeman7999]

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

[@freeelectron8261]

Great save using the SAD512 on a custom PCB. I liked the flanged minor sevenths too.

[@LeWernerSens]

Such men need the world. thank you for your value.

[@rondeledenis1948]

That was hot. Takes me back several years when soldering every day

[@ensewensew7305]

Astonishing knowledge and skill - Brill

[@trippntrev]

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

[@chaswinder]

Love your craftsmanship and cheerfulness!

[@stephenlamb90]

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

[@TexasGit]

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.

[@mjouwbuis]

They're obtainable, just not at a pricepoint that's comfortable for people who don't really, really, need them.

[@enryfrank]

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

[@JonnyFix]

I made a new years resolution to not buy fake chips. So far it's working. Nice tunes! I like to hammer on a ukulele

[@BradBo1140]

Omg, nice guitar! This was a fun episode.

[@williamt.swanson4861]

Another fascinating video . Thank you Mark

[@pebbleschan6085]

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

[@ashleycox432]

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

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

[@jim96r]

Great content and advice… Cheers Mark!

[@mrmansville9340]

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!

[@raindogred]

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

[@trojanorse]

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

[@EngineerLewis]

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

[@ianpritchard6375]

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

[@ricardoconti3868]

Any other technician would say " irreparable", but not Mark. Greetings from Brazil.

[@TheVdub1980]

You are something else wow. Not only can you fix most things, you can play guitar too!! Wow! I'm subbing!

[@philhunter9134]

One of the most involved music videos I've ever seen.

[@jameshartley5099]

Truly the renaissance man

[@lifeisfuneh]

Wow, last time I did this was probably 40 years ago ! You rock!

[@JH-si9oe]

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

[@drewwade9640]

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.

[@followthetrawler]

Awesome fix Mark - great improvisation.

[@kevinbowes1974]

Always learning 😊 thanks for your videos

[@absurdengineering]

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

[@jaccoonderdijk1777]

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

[@floppydisk921]

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

[@MrKillerno1]

Only honest hard working people get scammed. Sad. But, good news is, your video's are popular by enthusiastics, you do a great job, keep it up!

[@acme.videos]

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

Awesome work Mark, brilliant fix.

[@hansthijs]

Great job, well and thoroughly done😮

[@ChrisHopkinsBass]

I've got a late 70s, Mistress (the 2x9v) version that I got as my first ebay purchase back in 2004. Sold as "untested". When it turned up no sound. I found a pedal repair guy who thought the same as me that the SAD1024 was dead. Luckily the only issue was one of the 741s had died. He replaced it and it was good. I really needed to get that pedal down from the attic to test it as it's been 10-15 years since I last plugged it in

[@cjheeley]

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

[@em-dashman4404]

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…

[@RadioMarkCroom]

This absolutely made my morning, thanks Mate!

[@yt4krist0f]

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

[@russellforrest1730]

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!

[@Drew_Snydermann]

This man tools. Seems to always have the right machine for the job.

[@umbertoyltp]

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

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

[@paulwooller4524]

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 👍🏻👍🏻👍🏻👍🏻👍🏻

[@michaelgreenhaf6624]

You are a genius, Mark amazing skill level

[@a6cjn]

Once again, a most enjoyable video Chris

[@andrewrutter5753]

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

[@gtretroworld]

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

[@BeachCat]

Way to go! You could market those SAD512 breakout boards!

[@sypodj]

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

[@nickeva3964]

Very very impressive repair Mark, simply fascinating skills.

[@mikecumbo7531]

This video brought me back to 1982, I was taking an electronics class at college and we had to design and etch a rather basic circuit board and then build some device. Radio Shack, in the US, had everything I needed. There was a marker like pen that put a resist compound on the board, that created the traces. Any copper that didn’t have the resist marker would be dissolved by the acid.

[@ernestbarch2976]

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

[@bijanpal6948]

Excellent modifications....

[@the_atomshop]

really enjoyed that episode. Thanks!

[@retrogamer33]

Good repair Mark and nice guitar playing at the end.
