Very interesting set. Sony also sold a re-labeled 18/19"
tin can Admiral all tube set in the early 70's. This one was
a consumer set with ins & outs added. Still had tuners IIRC.
The add on was also US built but obviously of very low
production, the PCB almost looked home made. Strange they
used Admiral & not one of the better brands.
Do the inputs look like SC built or are they built elsewhere.
If they are SC then I would guess they also sold this under the SC
brand.
