This is Eico HF-22 schematic. One of the best output amps out there.
I own a couple, restored a few years ago. They sound great. No hum or anything.
It is an ultralinear topology.

As you can see, they do have B- at the GND, and it is not isolated from the chassis. The RCA inputs are bolted to it.

This is Mac, MC275. Same story. This is the original.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
