Today we troubleshoot and repair a LinnDrum with dead Toms and Conga voices. In doing so, I explain how the LinnDrum turns sampled data in the ROM into the audio you hear. We also look at a couple of upgrades I've got available that make the LinnDrum easier to service and repair and more enjoyable to play -- a replacement 5V power supply board and new sliders!
Parts, service and synthesizers available on my website. I buy broken synthesizers!

I just love the way u make something so expansive so easy to understand. Especially considering what u r fixing. People dream about owning them. It,s there next big thing. Dreams cost nothing. Paying for it costs everything sometimes. I have an Arturia matrixbrute, it was a huge buy for me. It was broken when i bought it i had to travel 300 miles to get it. It was the only one in Scotland that i knew about
TY for addressing the very limited replacement slider potentiometer options with these! You are an asset to the vintage gear community!
Hey bro.i just love these videos. Its a wondful insight into how you gentlemen work to preserve the things we love. Im sure, not a lot of people understand the impotance of this sort of thing. Kudos to you, Synthchaser.✊️
12:12 yes!! When I restored my Juno-106, I considered replacing the power supply - but a common aftermarket replacement which I won't name here, built on a few simple commodity switching modules, was being sold for $450! Give me a break! I spent some time and about $5 on parts to instead just fix my original Roland PSU.
Nice upgrade kit!
Thank You 👍
Amazing upgrades! Thank you Synthchaser 👏🏼
Fantastic, Synthchaser! I was wondering if there were any replacement sliders for the panpots; great to know that there are, and that they can be illuminated as well! The LM-2 takes me back to the '80s, when I was assistant engineer at a 24-track studio. Nice memories!
I officially put forward the motion that you should henceforth be called: Professor Synthchaser...!
Awesome!
As always, a great video. Also thanks for realistic and clever swap out solutions.
You make it look so easy. Been tracking the non working kick on mine for ages and cant even get a clean read on my scope lol
Amazing!
So the curcuits that make the sounds are just a shift registers pouring the samples from the EPROMs into a DAC. It's kind of like the analog video circuit in a computer drawing data in video memory on a CRT.
I'm just curious why you have the logo covered upon your DS1054?
🎉❤
still have pain I sold my unit .
Why no heatsink for your power supply design?

It's designed so no heatsink is needed.

@@Synthchaser that and semiconductors are somewhere between a bit and a lot more efficient than they were when this unit was made.
Thanks for the info about the alfa chip. I knew alfa made a bunch of other vintage chips but didn't know they made a 3320. That would have saved me a few bucks fixing an oberheim dx lol
