Anyone have a service manual or a schematic for this unit? I've been searching for close to 3years now with no success.

Adjustment rules/flowchart?

Great!
I have been looking for Newtronics 200 schematics for a while now.
My unit needs adjustments and as you know there are a lot pots in there.
Is there some kind of adjustment flowchart or anything that would help available? Manual would also help 🙂
