Korg M500 demo/ GENERAL TECH NOTE for later 70's korgs/ oliver leslie preview
Published on Sep 23, 2015 sounddoctorin
"Bob Weigel of http://www.sounddoctorin.com shows some new features I wasn't aware of on the M500 micro preset (ie. the ability to mix settings... why didn't I try this before? Some fabulous sounds available that way I'd never explored) , but also shows a problem that surfaced in both the unit shown here and my own M500. Be sure to open yours and remove the 220uF 16 V capacitors. Note how there is probably acid eating the traces under them. Restore as noted in the video and also 33uF capacitors were having the same issue in mine. THose particular values seem to be fail prone at this age. I assume the same parts were being used in other synths of the ear including MS series, PS series... possibly my PE1000 I should also check. Tuning is varying some anyway.. Look for discolored traces. Not hard to see. I also show off my home made horn for the oliver orbital sound projector I'd just finished at the end. :-)"
