Fw: [Amateur-repairs] Tube Female Contact Wire Brush
David Tanks
You can get a tiny wire brush, that I believe will fit into tube sockets, from Caig, the Deoxit people. It’s 4” long and 1/16” in diameter. I have one. It comes in a small, square plastic tube, which I use because if I ever dropped it I would have a hard time finding it. Look under Products > Caig Accessories. It’s called a Cleaning Brush, #B-SS116. It looks like it’s $12.95 plus shipping,

I have used DeOxit on tube sockets, not convinced it did much.
Anyone have a source of an abrasive rod, like a tiny diameter wire brush,
to run thru the female pins in a tube socket ?
On ceramic / Bakelite switches,. I have see references to fixing the tension
on a wiper contact, but no description how that was done. Is that a light
tap against the semicircular edge with a blade to squish it slightly ? Force
parallel to wafer so contact is not lifted ?
Regards, Dana.
