Circuit Overview:
     A 6 preset voice machine with the traveller filter with similar sounds to MS-10. There are actually two Korg 35 filters in these. One for the traveller lpf slider and one for preset arrangements. The first button accesses synth footages witha preset sharp attack. Second one gives you the variable attack and decay knobs. And two of the footage selects (every other one) are noise sources (white and pink). Third button gives you the traveller still but preset envelopes and the last three are preset filter settings with only modulations and portamento adjustments. Love that Tuba, bassoon and Oboe!


Service Tips:
      I can't recall what all I had to do besides filters on mine... serial 771129 I think it is. Ineresting, one on ebay is 791359 so maybe the 79 is the year of production in those days. I have 770098 in the PE-1000 and so that blows my thought that Korg was putting model codes in the first digits :-). Sooo... Anyway the manuals are online. Japanese capacitors seledom seem to go bad in these things. Usually connection or potentiometer issues probably.


Parts:
I probably have some parts for these. No clue who else would except probably vintageplanet.
