I owned Mr. Bs, products. I saw him preform a few times too. They called him Pimp Daddy, All about the Jazz. His amps were as good as they come and could drive a very hard load without a strain. He taught me how to pull wire from a spool and that is how he wired his amps. Same with the power cables he cold welded in place.
He took a pair of his amps and added knife edge switches for start up because of the cap banks (2) that were outside the amp chassis. They could suck a PG&E pole dry when they were being pushed, yet run cool while idling. It was a super rare thing to have power and COOL in the same box.. It just didn't happen. You could go from ZERO feed back to a TON with lock nut screw pots.
They were close to 150lbs for the 2 chassis mono blocks. He made 6 that I knew of. The first time I saw speaker cable heat up and get warm to the tough. He drove a 1 ohm bass load for over 10 minutes until a single 20amp shop breaker blew. We split the circuit and that never happened again.
15 years later I used the SST 2000 x 3 with his 3 speaker processor too. It wasn't digital it was pure analog. Man oh man could they make small planars and ribbons sing without the boil. There was never a question about the power cable either. HE made it permanent for a reason.
If I remember they were only rated at 1 or 200 watt @ 8 ohms, but would double down to 1/2 ohm (unpublished) if you wired 220/240.
Mine saw a lot of 2 ohm bass loads. It's always the same with me, I kept my Mac gear and keep on collecting.
I have pics of my speakers (Elixirs) with the SST Trinaural Processor and a stack of 2000s. Kinda cool!
