Nawww, #805 is fine.  It's the Minimoog that's giving me grief right 
now.

OT:  If anyone cares (I've already bothered Don and Mark about this :-
) ):
- I fixed the OSC 1 square wave being gone (yay), shorted transistor
- I've replaced the Pratt-Reed keyboard bushings (thanks to Rich at 
Archive Sound)---Major difference!
- OSC 1 still way too high by about 4-5 times (intermittent)...Kevin 
L. (Synthfool) had a suggestion I need to look at---may not be that 
blasted hardtoobtainium SG3821N (which has a new obtainium LM-series 
substitute---yay!) but a lowly 741 op-amp, which I have looked at but 
can't see anything weird about---will have to look harder or just 
replace it out of principle
- Squirrely keyboard...notes of a certain frequency (usually A, Bb, 
or B, depending on how the tuning is) send the keyboard CV input on 
the OSC board into a tizz...I don't think it's the keyboard but 
something in between.

At least poking around in that thing is a LOT more fun than 
working...which is *another* reason why the list---and M400 #805---
are so quiet.  :-(

...kl...Minimoog #6128 (not on top of M400 #805---well, only once, 
for a giggle)
