[sdiy] Cleaning assembled PCBs

[Robert Lorentz]

Whatever you use, do NOT use the "contact cleaner" they sell at radio shack

I had [have] a really neat WW2 era 'Knight' audio tone generator (tube
oscillator), but it was scratchy as heck on many pots.  I thought, oh,
I'll clean this right up by liberally applying my trusty radio shack
contact cleaner and working all the switches and pots

Wrong.  It ruined something (or more than one somethings)... guessing
it shorted somewhere.  Now when I power it up I get no output and
after a couple of minutes it smells like it's going to catch on
fire...


Side note, anyone happen to know where I can get a service manual for
that thing?  I've considered just pulling the transformers and concept
and doing something similar, but I really don't want to cannibalize
something that is a historic item.  Some people online want to sell me
one for $30 but I am skeptical and also think that is highway robbery
