I'm looking for a receiver for the office and ran across an old Technics SA-505. I've found a reasonable amount of information, but nothing as to whether it is tube or solid state. When looking at some of these older units, how can I tell from the specs?

Scott, here's a unit for sale out in Calgary, complete with specs. I don't know if it helps, or not....

It's 63 WPC, built in 1980, and not made by McIntosh or one of the other esoteric brands. It's pretty safe to say it's not a tubed receiver.

To add to what kcarlile said, it's my experience that mainstream builders of amplifiers sold and distributed in North America like Technics and other Japanese brands were entirely solid state from the 1970s onward.

In specs for a tubed unit, you might read the phrase "output taps for 4 ohms, 8 ohms, 16 ohms" for tube amplifiers that used output transformers, many of which did.

Thanks. That's the kind of info I was looking for. I saw the one listed in calgary, but there was also one listed here in New Orleans, which prompted the question.
