How to test the power supply of your ARP Synthesizer Keyboard

I made this video which shows how to test the power supply of an ARP Synthesizer.  It was intended for someone with an ARP 2600, but I’m demonstrating with the power supply of a Pro Soloist, and the method shown can be used to test the power supplies in all models of ARP synths.  To do this test you just need a multimeter, the intended audience doesn’t need to be electronics wizards or even know how to use the multimeter.  If your power supply tests bad, I can repair it or supply a modern, upgraded replacement.

Oberheim OB-Xa Analog Synthesizer Repair Video Series

I’ve made a video series showing a repair/partial restoration I did for a customer’s Oberheim OB-Xa.  In the first part, I show what’s wrong with this keyboard and rebuild the power supply and voice cards:

In the second part, I rebuild the Pratt-Read keyboard and change the bushings.  I also repair a broken switch on the bender assembly:

And finally, I calibrate the power supply and voice cards:

I sell kits for everything I restored in this video (power supply, voice cards, and key bushings).  If you’re not comfortable with a soldering iron, I can also perform these services for your synth, just drop me a line.
