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
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!
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
Just when I think you cannot impress further, you push the bar even higher. Your channel is a never ending source of education and entertainment. Thank you for taking the time to make these videos Mark!
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!
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 !
@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 🙂 ?......
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.
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!
@@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.
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
Excellent fix, as I recall Electro Harmonix made two versions, the Electric Mistress and the deluxe version, I have owned both, way back, trying to simulate a Leslie organ cabinet, I was given one that had been installed in a box, for free standing rather than floor use, I sold it for a considerable amount, maybe somebody was buying it for the components !
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!
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.
Is there no end to your talent ! Last video I saw you replaced the writing on a Technics amp as the cleaning foam you used erased it off the brushed metal plate on the front! And now you're designing PCB boards and replacing an IC and using a modern equivalent - somehow making it work! Then to top it off... a bit of guitar at the end! Genius! Wished you were closer, I'd love to come to your workshop just for a visit - and maybe learn from the master!
...you can also play guitar. That's awesome. I've been watching several videos. You are a GREAT technician. They are hard to find anymore. You have great equipment and great instruments. Congratulations.
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…
Nice! And be careful with fake components. I Know a guy who had bought 8 voltage regulators from the famous Chinese website for use in a pre amplifier. Four of them were dead straight out of the box, the other four stopped working within a few weeks after the amp was in use. After that, he replaced them by genuine ST branded regulators.
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.
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.
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.
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
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.
felt so bad for you mate when it turned out those chips were duffers but you have a really positive personality. I'd like to be more like that, it's a better than feeling annoyed all day which is how i would have reacted😊
Gday Mark, bought a Caps set for my amplifier and a supplier from bulgaria, was fast and all looked fantastic, until I sent a pic to my brother who got the same only to be told by his elec tech they were fakes. 😢. Disappointing when you expect something for the money. Just as well we didn't get them soldered in! Enjoyed watching you vid. Cheers from Tasmania Australia a long way from Bulgaria!
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!
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?
I've used Ideal Industries strippers for years - fabulous tools. People seem to like the auto clicky things nowadays but for the old fashioned types these are reliable and sharp.
Well done sir ! I’ve also had the pleasure of buying fake chips . Always disappointing. And the sad part is they weren’t even that expensive of a chip or very rare to begin with . Just never know what your getting anymore!
Thank you very much! I’m due to film a new one over this weekend- I haven’t decided what it will be yet, there’s no shortage of gear to fix! Cheers! Mark
Awesome video as always. Electrician for over 20 years and those ideal strippers are the only ones I will use. Always bugs me to see electronics guys use crappy strippers.
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.
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
Mark, Really happy that you found the wire strippers useful! I've had a few Electro-Harmonix gadgets in my rock-n-roll days. LBP-1, and a Mike Matthews Freedom amp. Freedom because it also was battery operated. Mike Matthews was the founder of Electro-Harmonix back in the70s. Thanks for the acknowledgment. Solder on!
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.
Hello sir, Congratulations for such quality videos and thank you very much for the knowledge you give us. If you can, show us the isolation of the oscilloscope, the signal generator, etc. And in general the isolation of the devices from each other and from the power supply network. Be always smiling and healthy. Greetings from Greece.
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 👍🏻👍🏻👍🏻👍🏻👍🏻
They used to make DIP socket extenders like you made; sixteen double ended posts held together with PE plastic. Don't know if they're still available, as I haven't done bench work for years. It's good to see I'm not the only one that clumsily burns myself. I hope your customers appreciate how far above and beyond you go.
Great stuff Mark. Whilst making a MXR clone flanger, I purchased a ' cheap' delay chip from ebay only to find it was fake. Bought from a UK supplier and it worked a treat. I suppose you get what you pay for. Keep fixing.....
Wow, not only an electronics genius, but Mark also plays guitar 👍👍👍
Yes, I was impressed, he's awesome!

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.

Подумал - Сашка Лаэртский, ан нет. Но когда в конце заиграл на гитаре - засомневался ) Спасибо, вы очень крутой спец!
It’s always a great day when Mend it Mark uploads a new video. Thank you!
As usual - very clever and resourceful repair. I think I might have added a power light as a bonus.
A 12 volt led doesn't cost the eart, and a hole isnt that akward to drill with a "splodge" of glue 😂😅😂😅😂
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!
Not as consistent but an iron strip and a hammer will also do the trick. But Mark's way is more elegant and professional.
@@paulmichaelfreedman8334 You could also use a socket with long pins

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 😆👍
That really took me back to my CDT lessons, I loved making printed circuit boards like that 😊
Brilliant! Love watching your repairs - its the chuckle that's the icing on the cake!
Excellent fix, as I recall Electro Harmonix made two versions, the Electric Mistress and the deluxe version, I have owned both, way back, trying to simulate a Leslie organ cabinet, I was given one that had been installed in a box, for free standing rather than floor use, I sold it for a considerable amount, maybe somebody was buying it for the components !
The counterfeit market makes things super frustrating! I loved that you made your own PCB for the replacement.
Wow solid work! 😀 Lovely bringing a device like this back!

...you can also play guitar. That's awesome. I've been watching several videos. You are a GREAT technician. They are hard to find anymore. You have great equipment and great instruments. Congratulations.
I am impressed with your road to succes towards half a Mistress with satisfying result!
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
Always impresses me and admire your professional workshop equipment and your creative skills it's simply amazing! Greetings from Budapest, Hungary :)
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…
... 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!!
Hi , I just want to say how much I enjoy watching , you are brilliant at making the very technical repairs interesting and fun.
Nice! And be careful with fake components. I Know a guy who had bought 8 voltage regulators from the famous Chinese website for use in a pre amplifier. Four of them were dead straight out of the box, the other four stopped working within a few weeks after the amp was in use. After that, he replaced them by genuine ST branded regulators.
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.
Any other technician would say " irreparable", but not Mark. Greetings from Brazil.
This is more like a manufacturer workshop ( milling, drilling, fabricating etc). He must be a genius!
Is there no end to this man's talents ...........................................
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.
Im so glad i found this channel. Please more of these. So cool.
I've watched many of your videos Mark .. and there's always another bit of kit! Wire roller ... chip straightener - awesome
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.
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
Best channel out there.
my main interest in electronics is audio..guitars, pedals amps, mics, preamps, mixers..love these ones
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.
They're obtainable, just not at a pricepoint that's comfortable for people who don't really, really, need them.
What an amazing fix. Found your channel recently and am loving it. Real hardcore techie stuff.
Respect, this brought me back some solid memories of lessons creating boards using nasty chemicals, awesome!
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.
Amazed that you went straight to making an adapter PCB without testing the modern chip on breadboard or similar. You know what works right away.
felt so bad for you mate when it turned out those chips were duffers but you have a really positive personality. I'd like to be more like that, it's a better than feeling annoyed all day which is how i would have reacted😊
Love to read those schematics with you. Takes me back, very very satisfying.

Demand your money back or leave bad feedback or both
Just wait until you receive fake chip sockets!
Thanks, Mark. I love your presentation style and excellent production qualities. Cheers!

You are a genius, Mark amazing skill level
Chip straighteners? Who knew? That was really interesting Mark,even though a lot of it was over my head🙄Nice Strat BTW
This man tools. Seems to always have the right machine for the job.
Always in awe of your capabilities and skill Mark. Outstanding work as always.
It's great to watch a genius at work. A man of many talents.
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!

Omg, nice guitar! This was a fun episode.
Love your craftsmanship and cheerfulness!
Always enjoy to watch Mark working, so good working methods, cool tricks.
The guitar was the cherry on top of the cake!!

Thanks Mark for the expert troubleshooting and repair lesson! ☺🙏
I applaud your determination.
Also your victory 👍
Really enjoyed the design and build of a “custom” chip👀 superb.
Amazing video with so many twists and turns! Let’s make a PCB and get the Strat out
Musical Mark Mends it. Well done ! 👍
It's all far too technical for me but it didn't stop me enjoying a great innovative repair and an impressive determination to fix the device.
One of the most involved music videos I've ever seen.
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 👍🏻👍🏻👍🏻👍🏻👍🏻
Great work, Mark.
got the same pair of strippers in my college electronics kit and they stayed quite sharp for around 12 years.
They used to make DIP socket extenders like you made; sixteen double ended posts held together with PE plastic. Don't know if they're still available, as I haven't done bench work for years. It's good to see I'm not the only one that clumsily burns myself. I hope your customers appreciate how far above and beyond you go.
Great stuff Mark. Whilst making a MXR clone flanger, I purchased a ' cheap' delay chip from ebay only to find it was fake. Bought from a UK supplier and it worked a treat. I suppose you get what you pay for. Keep fixing.....
Remember buying one on these NEW!! Absolute cheap rubbish! extremely noisy! Nice work Young Mark!
