contaminated soldering surfaces
"Jeff Liebermann"
Peavey Prowler amp from 1999. All the 1/4 inch sockets and one , only, of
the valve bases , bad solder joints, reacted to the re-soldering process
as
though the tags were made of stainless steel or had a grease/oil film over
them. What could have been the cause?
My guess(tm) is that the lugs were cadmium plated.
** Whaaaatttt ??
Cadmium can be
soldered with silver solder, but barely with regular 63/37.
** How are high volume manufacturers like Peavey supposed to use you
imaginary parts in automated soldering systems ?
Wot ********.
