We made it to Episode 100! Hurray!
Forging ahead on the ARP Quadra restoration, I give you an overview of what the Quadra does and what’s inside of it, and we get started recapping and testing the power supply and several other boards.
Repaired this Rhodes Chroma Expander that wasn't booting#rhodeschromah#vintagesynths#synthrepaire#analogsynths#SynthTechhtech
Working on a couple of ARP Avatar guitar synthesizers. The "magic" of string frequency to control voltage conversion is in the epoxy filled E' module, though the design never worked so well. If only ARP had brought the Chroma to market instead of the Avatar and the Electronic Piano... Elsewhere one of the power supplies has a filter capacitor that leaked through its vent, and the other has a burned up current sense resistor (scorched all the way through the PCB, too). Smoke coming from the synth wasn't the intended way to sense an overcurrent situation... ![]()

I don't usually talk about my clients or where the instruments wind up, but this one was too cool not to share...![]()
