I have an SA-7100- not as nice looking as Glen B's- but my sister found at a thrift for $10 and it came with a Kenwood KT-5500 that works, except for all the dial lamps.
This amp does sound surprisingly nice for a lower model in the line. I'm planning to use it in my office system, once I get it cleaned up.
The engraved lettering is a nice touch, as is the wood case.
