GTE Sylvania
Most likely.
Those BSR turntables have an awful reputation, so bad the company sold their genuinely good semi-automatic systems under another name.
And, yet - they have held up better than the Garrards of that era and as well as the V-M turntables which, by this point, were actually running magnetic cartridges at 2g or less without difficulty.
Solid state, of course, and I don't know anything about that, but I'd guess the sound quality by that day's standards was considered adequate for one's great-aunt Agnes and her hearing-aide. Those early solid-state amps were awful.
Pretty cabinet. One reason I think it may be a Sylvania. They did nice cabinetry.
