Crumar MagicVox Electronic Accordion

[mikem245]

I am looking for any help with repairing my accordion. The problem is that I have lost the Preset Flutes and the Orchestra tones also the Percussion and Brass on the bass side, all the pianos,strings,volumes work. If anyone can help I would appreciate it. My e-mail is: mikem245@verizon.net

I have several CRUMAR generators (2) MGVX and (2) CD that I am repairing, they also have the same problem with the flute presets not working. Strings and basses/chords work, just no flutes.

Schematics for these units seem to be rarer than hens teeth.

I have schematics, flutes and orchestra don't work on my MGVX

I have the schematics, I don't know how you can do anything on the Crumar MGVX generator, the circuits a very complex, even with schematics it,s difficult, you need a good scope to trace wavforms, no waveforms or test points are on the schematics.
