Upon the date 02:43 PM 4/22/99 -0800, Zane H. Healy said something like:
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.
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 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.
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
