Audio research VT200 Biasing & Schematic

[dischief]

Since Audio Research Corp. will not provide a PCB schematic for the biasing of my VT200 behemoth I would request anyone with a circuit board scan and/or schematic to come forward. Although I can do this with merely their 2 page biasing instructions I also know any tech, even at ARC, would refer to a detailed image of the printed circuit board component values and test points.

Thanks,
John

sure would be nice to get the service data for this machine. everytime you ask anybody they send the bias instructions or the schematic. but where SERVICE DATA?

its a little bit silly the silk screen has nothing and the instructions are sparse. I would imagine there is a service manual but its buried deep.

ARC does not usually provide more than that.

If you need more than the schematic and parts list, you probably should probably reconsider playing with this unit.
