Default CM labs 920

Anyone know anything about this amp? I am considering buying one and would like to know what to look out for in terms of possible problems. I owned a CM labs 35wt/channel amp years ago and drove Frazier Super Texans with it. It was built like a tank and sounded very good. Is the 920 in the same league? Thanks

I own one in need of repair. It uses the hard-to-find 2SD555/2SB600 TO-3 outputs, long discontinued, and frequently counterfeited.

I had a 100W per side one when I was in Colorado. Blew up three times. They only fixed it twice, so it became a mono amp. I guess an instability issue. I was not impressed. Replaced it with a Sayno Plus 100 that a: worked, and b: sounded better. That was eventually replaced by a B&K 140. , and now Rotels

Based on my hand-drawn schematic, it doesn't seem to have much protection apart from a DC output fault relay.
