Early 70's Studio P.A.
« on: January 01, 2010, 04:32:46 pm »
i just bought an early 70's Studio P.A. head. There is an unlabeled jack right between the two KT88's in the back and I need to know what this is. I plan on running this head through another and wont even try it until i am sure that this mystery jack is, in fact, a direct out. If anyone can shed some light on this, it would be much appreciated. Thanks.

It's not a phone jack, it's your bias adjust pot. A recesssed screwdriver adjust pot.
