Synthchaser #080 & 081 – ARP Odyssey Restoration & Repair

First, we restore a dead ARP Odyssey. Not the new Korg one, a real vintage, 1973 Mk 1 Model 2800 Whiteface ARP Odyssey. We change the ICs, capacitors, sliders, repair a dead oscillator and a damaged power supply. This Odyssey gets the full Synthchaser spa treatment!

Then, we use that ARP Odyssey as a test bed to fix a customer’s Odyssey oscillator board.  Customer was reporting his Oscillator 2 couldn’t be calibrated and was drifting. The trimmer should be adjusted to make a 20Hz square wave, but the lowest it would go was 40Hz. What I saw was cool enough that I had to edit it into a Synthchaser video!

Synthchaser #076 – ARP Omni 2 Wood Side Panels

I was restoring an ARP Omni 2 and one of the leather sides was damaged, as they often are, so I made some replacement side panels from hardwood. In this video I pop them on we see what it looks like when it’s done. My video camera is lousy, and doesn’t do the wood justice, but you can see the panels better in the stills at the end.

I don’t currently plan on stocking these, but if you’re really interested in a pair, contact me, because it turned out so nice, I’m sure I’ll be making more.

Synthchaser #072 – Fried LinnDrum Repair

Two customers bought LinnDrums on eBay and sent them in for service/repair. One customer got a good buy, the other got a nightmare! It was a hacked mess of wires and modifications and the circuit board was blackened all the way through from heat. When most people would consider something like that a “parts machine”, our bold Synth Chaser forges ahead. Will he bring it back to life, or has the Synth Chaser finally met his match?

matrixsynth.com’s Oberheim OB-Xa repair video series

For your viewing pleasure, I present Synthchaser #069 and #070…  A 2 part video series where I repair an OB-Xa for Matrix of Matrixsynth.com.

One voice card is dead, and others are failing autotune and sounding really inconsistent from voice to voice. In the first video we take a look at the state of the synth, and troubleshoot and repair the dead voice card.

In the second half, I continue the repair by rebuilding the power supply and voice cards, and get the synth in tune and sounding consistent from voice card to voice card. I also show you a common defect with the voice cards that prevents proper calibration.  Lots of time lapse soldering with looping music.
