Have anyone pics and tech-data for a SU-1 step-up?

Mine had a list price of $3500 when I bought it in the early 1990s. Got it used then for what I sold it for 3 years later. I did not know of any subsequent price increase; indeed, I doubt if there was any change to it, not much you could change, so don't see why there would be an increase.

Frank,

I have seen and heard an SU1. It sounds just fine and very quiet (no hum pickup). It is very big. I'd say 12" wide by 10" deep by 8" high (30 x 25 x 20). Must be heavy, too. There is a lot of shielding and the transformers themselves are supposedly quite large. It's quite unique.

My guess is that the gain is about 26dB (20:1), having compared it to my new step-up. RCA jacks in and out.
