Well, in getting the area around the /44 cleared up I discovered that I've
got a M9302 after all, of course there is a reason that they weren't on my
inventory list. All the capaciters on the board are pretty well smashed.
The printed circuitry is also fairly badly corroded.
I think I can probably get it cleaned up enough to use temporarily at
least, however, I need to know what size of caps I'm supposed to use (yes,
they're that badly smashed.

My thanks to both that provided the info, I kind of figured they're be at
least a couple people with that info. Now to make a run to the local
electronics place.

Use Scotchbrite or steel wool to clean off the corrosion. *Make sure* you
get all the steel wool bits out either by blowing off with air hose or
running through dishwasher (if your wife doesn't catch you ;) Scotchbrite
under warm water is best though. If any bare copper traces show now, cover
the edge conns and shoot the solder-side with clear enamel or perhaps clear
shellac spray to protect from further corrosion. This has always given me
good results when I do pc board restorations.

I'm not near my 9302's to check but if they're 0.1 mfd I have a ton of them
(well, a thousand or two pieces . . .) Either axial lead glass-encased
ceramic or radial disk ceramic both at 50 WVDC. Let me know if that's what
the value is and I'll send you what you need. If they're 0.01's, then I may
not have any but I can do some heavy digging to check anyway.
Regards, Chris
