Analog synthesizer repair, parts, sales, and innovation. I buy broken synthesizers!
Vintage synths are cool. But a lot of the time, they’re nasty inside. Dust, spilled beer, rodent piss, even pubes… Everything gets inside. In this video I show you how I wash dirty synthesizer circuit boards in the sink.
Warning! Dirty synthesizer pictures in this video!
In this video we track down a problem that’s causing a range of keys to be dead on this Oberheim OB-Xa. I explain what a switch matrix is and how it’s used by synthesizers to scan the keybed–this is still the way things are done today! And we use our new knowledge of switch matrixes to repair the OB-Xa.
I couldn’t pass up the opportunity to repair this rare and interesting early sequencer made by Roland. Very few of them were made and even fewer still exist today. But there’s no service manual or schematics!
So we have a look around inside and see what makes it tick, and I show you an approach I use for tracking down problems I don’t know I’m looking for. And after it’s fixed we take a peek at it in action. It’s hugely different from other sequencers of its time.
We see what the Sequential Circuits Piano Forte / Siel PX electric piano has to offer and see if it’s worthy of the Sequential Circuits name. We also peek around inside and see how it works.
Wrapping up the restoration of an ARP Omni 2, I had one problem left to fix. Static noise in the output, but only on the Strings. I show how I track down and repair the problem.
Buy this ARP Omni 2 while it lasts!

A customer was told by another tech that his vintage ARP Odyssey’s filter was dead and would need to be replaced with an aftermarket filter. The customer liked the sound of his filter so he brought it to me and I de-encapsulated it and fixed it so he could get back the exact sound he valued his vintage Odyssey for.
Demo of the 40 factory patch sounds from the Prophet 5 (Rev 3.2). This is not intended to be musical, just a demo of the sounds. I am far better at fixing them than playing them.
Buy this Prophet 5!
Sequential Circuits Prophet 5 Keyboard Synthesizer Pro Overhauled Rev 3.2 Excellent
Over the previous 6 videos, I repaired and restored a broken Prophet 5. Now that it’s all fixed up, in this video, I show how to load the factory patches into the P5 via the cassette interface.
OMG! The long awaited 6th installment of my my Prophet 5 restoration video series has finally arrived!
Last spring we mostly restored a broken Prophet 5, but I got busy with customer repairs and never finished it up. Today we’ll track down and repair one final problem with the P5… Seemingly random out of tune notes.
