yo peeps - any help or guidance appreciated.
I have a problem once one of my decks warms up.
after a few minutes it goes mental if the pitch is moved from 0.

in a minus direction it is fastest near to zero, then slows lightly towards -8

In a positive direction it seems constantly fast.

I suspect this is associated with d301 or associated circuitry, but if anyone has any experience of this issue, your input would be welcome :)

Not seen or heard of this before however likely to be connected to pitch control switching or pcb. Try some switch cleaner otherwise grab the soldering iron.
