I don't have it. Did you look at the TRA960.4? If your amp uses the SG3525 driver IC, it may be close enough to be of some help.

Hi Perry, thanks for replying. I just checked on Ampguts, the TR and TRA (later series) are totally different amplifiers.

The TR were of the same era as the Van Goghs, designed by Karl Cummings. While some think the Tarantula TR 500/4 and VGA 500.4 have the same internals, they have not, which can be seen by looking at pics of the boards. However, they resemble each other more.
I do have the Van Gogh VGA 800.5 schematics which could come in handy in case of future problems, but I'd rather have had the TR 500/4 schematics. Emailed Soundstream, they only supply schematics to authorized dealers, which I definitely am not

I am adding this specific amplifier to my growing collection of amps, and of each amp I own I like to have the schematics or even better, complete service manual. But you can't win them all.
