Common Service Issues/Tips:
Parts Sources: Keys knobs semiconductors misc
Uncommon chips/modules used: SAA1030 master oscillator (TOS), TDA0470 transistor arrays, 14pin 709 and 741 op amps, SAJ110 = SAJ410 dividers
General Info Links: VSE synth or VSE String





Circuit Overview:
     Divide down from TOS with a lot of waveshaping like Omni. I'll review more when I have time.





Service Tips
     Probably a lot of tantalum capacitor problems like Omni. I worked on one that had lost output and turned out they used a 741 in the 14 pin package I think I recall. Glad I didn't throw those away! :-)


Parts:
Lots of discrete parts in these. I have a scrap Omni Mk 1 unit with no upper board. Always feel free to ask or check my Parts
