Vintage Synth Repair

>>1.  How do I clean the inky mess off of the electronics?
2.  What should I use to replace it?  Are there any diagrams showing
the insulator's proprer placement?<<

is that the bill fox that I know? 
well, anyway... this gooey mess is a common problem with the t2, the
rogue & several other moog products from that era. 
first up, you don't necessarily need to replace this stuff unless you
are worried about dust getting into the faders. if you think this is
going to be a problem, then you could probably manufacture something
suitable using thick polythene (like the clear sleeves you used to get
for LPs) & a craft knife. it needs to approximately match the
apertures in the control panel; perahps the best approach would be to
apply a layer completely over the inside of the panel (rather than try
to "sit" it over the pcb) & cut holes where necessary.
tbh, I didn't bother with my rogue, & it's been fine for 15 years.
ymmv.

the annoying part of the job, whilst more tedious than tricky, is
cleaning off the residue. I've heard mixed opinions on this stuff-
some say that it is partially conductive & that in the wrong place it
will cause problems. this has not been my experience, though it's
presence certainly hinders other service ops & looks unsightly. I used
isopropyl alcohol (I can't remember what this is called in the US-
denatured? same stuff you would clean tape-heads with, anyway). try to
avoid getting this in the faders themselves, as it may damage the
carbon track, but it won't hurt anything else. & let it all "boil off"
(an hour or so) before firing the synth up again.

good luck!
