I found this on CL today and has to probably be my coolest piece of audio I now own, and my first piece of tube gear. It has a Motorola HS-621a chassis with what looks like all original tubes, if that makes a difference. I know nothing about tube gear, so this is all new to me. It doesn't look like it has ever been apart or worked on. I just think it's so freakin neat that I wasn't going to pass it up for $40! Hell, it even has a 3-way speaker system in it! :thmbsp:
