The Hobby Stop might have some, dunno if that small though. I'll sure check
when I'm there next. Its about a 60 mile round trip from here.

I know for a fact that wd-40 will carbonize like crazy, you can't use it
anywhere near an electrical contact carrying a load, like a headlight switch
unless you let it dry for days. LPS1, being a similar wax in carrier
product, would probably match it in quick carbonization.

Oh, I'd assumed a goodly portion of it was hydrocarbon breakdown products. My
bad.

Unless I can con the local telco out of one of their 75,000uf x 75 volters,
its probably going to have to do w/o. I went googling for big caps last
night and came up empty, everything is lower voltage for transistors now.
Thanks Jon.
