Moog/Cordovox CDX-0652 aka "White Elephant"
Repaired 2022
This synthesizer/organ was nicknamed the "White Elephant". It was built in Italy in 1974 by Cordovox. It combines a Thomas organ with a Moog Satellite shared on the upper manual.
Lots of work done on this one! When it arrived, many of the notes didn't work, and the synthesizer made no sounds. I got everything working 100%, eventually!
Work done: fabricated new key actuators for synth section. Fixed divider causing top synth note not to work, repaired synth signal to main output, LFO on synth, replaced TDA-470 transistor array that was causing missing footage on organ's G notes, replaced filter supply capacitors on synth and organ, cleaned all controls and key contacts, replaced missing white fader caps on synth section with Vestax caps.
