Odds are it's rebranded by B-A by some Japanese manufacturer.
Since this seems to be built for the company selling it, I assumed that it was a dummed down version of something else with smaller iron and perhaps less glass. I'm not at all sure that there ever was anything in that spot but it was cut that way for a different model. Just a WAG, but that's what I thought.Missing a can cap (see the picture looking down from the front), funky looking wiring from the output trannies to the speaker terminals, tubes tilted in their sockets. I wonder what they mean by "tested and working"?
Oh yeah, wouldn't be at all suprised about that, LIC was the promised land for audio manufacture in those days...Possibly manufactured out of LI City in Queens?
