Alright, Here's the secret to loosening up
tapco pots... Get some Dibutyl phthalate
and squirt a drop or 2 at a time down the
shaft at the top of the bushing and turn
back and forth. It shouldn't take very
much to free the pots up. The po ts get stiff
especially when they're cold as you've probably
found out already. You don't want to use too
much because then the pots can get and stay
too loose. Also, try to avoid using tuner/
contact cleaner if you can because it can
make the pot goo (the stuff that is sticking)
get onto the resistive element and make the
pot scratchy (electrically).
I'm not sure of a good source of Dibutyl
phthalate, but if I find one, I'll post it.
A good chemical outlet should have some.
Let us know if you find a good source.
It's a clear liquid and I know there are
references to it on the internet.
The pots themselves were made by CTS.
They were kind of special for tapco.
