Let me snap some and post back.

Sorry, forgot about this post. I ended up fixing the stereotech tonight. The unit powers on and comes out of protection.

Before I hook speakers up to it I want to dial in the bias. Still haven't found the instructions on how to!

dc offset

The bias adjustment pots are identified as VR607a,b on schematic (page 21) and location view (page 27), but they are identified as VR601a,b on printed circuit board view (page 20).

There is no offset adjustment tough.

Respectfully speaking,
Would not the adjustment pots VR607 a and b on the schematic be for DC offset since they are associated with the class a amplifier

I was incorrect

I beg your pardon, I was incorrect

I just acquired a stereo tech 1200 that was messed with by a pot twiddler.

what is the procedure for adjusting vr607? or, the best approximation on a procedure. there is nothing documented in the service manual that i could find.

I know this is an old thread, but figured it would be best to continue this one then to create a new one
