Hmm... From "and I don't think my string section is working..." I would
assume that the brass section IS working which would rule out the MK50240
(then all notes would be dead). Concerning TDA1008 there's one per voice so
if one of them were dead you would lose just one note out of 12. As for
availability, TDA1008 is pretty easily available costing <$10.

So if the brass section is working the critical stuff (SSM 2040 and SSM 2050
in the later versions) are OK, the string section is just a bunch of 1458
and 741 opamps.

"also seems like the EQ switches don't do anything" - they shouldn't. EQ
only applies to string section.

Best regards,
Margus

For me it seems that the Top Octave Generator (TDA1007 or SAA50240) is 
defect. There are replacement parts for such Chips, but they cost much 
money.
