Indeed, a Motorola Model 23SF11M-FMZ. Surprising none of guessed this brand, and the clue was in the picture in the ad, just too small to read:
It has tuners for TV, AM and FM
and has an outboard MPX for stereo.
Three channel (tube
) amp with a 10" Golden Voice speaker and two 5" satellites. Power tubes are 6GK6s, which is one I have not seen before in a Motorola. It is a repinned 6BQ5 I believe. Only two power tubes yet three OTs. I have seen this with the cheaper Motorola 3-channels, but both of my Moto consoles have separate power tubes for each of the three channels.
And now for the TV chassis. The date is revealed here: Oct 1962.
He says that the picture tube is dead. Is that something I could test on my PACO 640 tube tester?
Oh, yeah, has a pretty clean VM record changer, too.
All this for $20.
