Synthchaser #099 – ARP Quadra Restoration (Pt. 1) – Testing Membrane Panel

It’s finally time for some ARP Quadra restoration videos! I’ve been sitting on some broken Quadras for a while and have finally found a good home for one of them. But, before I can commit to selling this Quadra and get underway restoring it, I need to know if the membrane panel works.

So in this video, I show you how to test out the membrane panel. Important to do if considering buying a broken Quadra, or if you have a Quadra with some bad switches.

Synthchaser #098 – Oberheim DSX Sequencer Repair

Today we repair an Oberheim DSX sequencer that was sparking and smoking when I first turned it on. We clean up nasty battery corrosion, repair a short circuit, rebuild the power supply, replace a broken display, install my battery eliminators to make sure we never have another leaked battery, and we test the sequencer with the diagnostic ROM and with a real OB-Xa synthesizer.
