A Bozak power amp? I didn't think Rudy Bozak made any power amps. Anyway, some Bozak history:
Rudy Bozak was a well respected speaker builder in the '50s and '60s, offering huge systems with multiple drivers and great sound in its day. With the introduction of the AR-1 and smaller bookshelf systems, these larger systems fell out of favor and Bozak eventually disappeared from the market.
The amps were probably built by another company for Bozak. I imagine it's a very good quality amplifier.

Yes, I used to build those years ago when I lived in the same town as Bozak and worked there briefly. The amp may not be a total piece of crap, but it's probably not what anyone would consider high quality using modern criteria. This was admittedly a very long time ago, so I suppose you could test it for distortion, noise, and frequency response and arrive at your own conclusion. But as I recall it was not an amp I'd want to own.
