OK, an Inverter that does 350 WPC @ 4 ohms and 0.00000000000001% THD will be nice. Time-varying system behavior must be minimal or non-existent......and none of that THD+N crap! Just keep the notch filters in the drawer!  :)
I got the deluxe kit, it had a solar cell and a meter.

Hmmm....so it was just the other day, really! It was.....

The mysterious RobKen Pre Amp, # 22 of 23 shows up. :)

Maybe next time I'm at Robin's he will pop the cover off for a few pics?

The name on the back of the RobKen preamp is Greg Johnston...

Greg was an owner of Trace Engineering and Magnum Energy.

Steve Johnston's brother. 

I remember when Greg was one of the production leads at Phase Linear back in the early 1970s

Robin still has the working prototype of the SA P-202 amp. I did not get any good pics of it except for one SCAMP board. Again, next time up to Arlington maybe I'll have the chance to get some nice pics, along with more of Robins SA gear he is taking out of storage. All the SA gear he has is going in a big system soon to be up and running. :)

Hmmmmm....been a couple years. I did say I would post some topless pics of the RobKen Model 5000. Well, I was out at Robins recently and he was looking for a good home for the RobKen and several SA prototype amps and pre amps. After twisting my arm just a little...I agreed to adopt them! :)

A few pics of the RobKen topless....More to follow!
