QUESTION: Hmmm....Lovely!
I would like to know wattage per channel; How many channels; configurability; THD; Ohm load capability; How she sounds (I have heard early Nak, PPI, US amps, and really liked them all) ((My all time favorite was an Adcom 4702 which got ripped out of my world/car unceremoniously one evening)) How to get an adaptor that fits the din plug for it, or alternatively, what is the wiring layout so I can actually hook it up; and, finally, anything about this amp that you are aware of that makes it unique?  Very cool that you have one!  I just stumbled on it for $5 at Goodwill in very good shape.  Were a lot of these made?  I spent hours online looking for info on this to no avail.  Sony doesn't have ANY info on them anymore.  Crazy.
Thanks,
Bruce.
