Hey Fixer-guys,
Its been awile since I have been inside a BA of any type. Actually this current project is not on a true BA, but pretty darned close... And I suspect what I ask and what you will tell me applies to BAs... so I'll ask.
I had an electrolytic cap blow inside of a radio... 315V, 10uF, looks to be the filter cap tied to the grid of a 12BY7A driver tube... I discovered it by accident when opening up the radio to fix an intermittent connection inside someplace. I found it by discovering the oooozy-slime all over a ckt board of trimmer caps and the bottom RF Cage cover.
So, what is the best way to get large amounts of this nasty sludge off of a significant number of components that have been covered/mummified in this goo for a long time? I bought the radio from another guy (not on ebay) and I was never told it had a problem like this. I have never transmitted with the radio, so I'm sure it was this way when I got it.
Looking for advice. I have heard using alcohol and qtips are one way... but that sounds like using a very slow process, like using an eyelash brush to unearth a triceritops skeleton in South Dakota.
Advice appreciated.
Wayne, ke0ms
