[Mgs] soldering corroded copper

[Rick Lindsay]

Thanks everyone.

I've since cleaned the board, soldered all the connections, and carefully restaked the rivets.

I cleaned it with a wire brush, scraped with an Exacto knife and coated each connection with solder flux before soldering.  I then cleaned the flux away with braked cleaner.

One correction.  The substrate is actually 2mm thick phenolic, not glass fiber.

The board is back in now and working perfectly.  Thanks again for the sage advice.
