Just acquired a Magnavox tabletop Stereo model FM 28 and need some info and help

[vortalexfan]

Yesterday I acquired from someone on Facebook Marketplace an early 1960s Magnavox tabletop AM/FM Stereo radio model FM-28 that I can't seem to find a whole lot of info about and what info I can find about it it seems to call it "The Penthouse" and its one of those AM/FM Stereo Radios that had a Woofer and tweeter in the main cabinet and then had a remote speaker cabinet that made it become stereo (the stereo electronics are already there, but you had to have the remote speaker attached to get the "Full Dimensional Stereo" as Magnavox seemed to dub their stereo technology back then.

The issue I have with mine is that mine is missing the original remote speaker (stereo) speaker, and I was wondering if it was common for that speaker to go missing over the years (like how some of the old Magnavox consoles that worked the same way also seem to be missing their remote speakers sometimes) and how common it is for those remote speakers to show up on eBay?

Other than missing the remote speaker the unit works flawlessly with its original parts yet and has all of its original tubes in it yet except for the output tubes and one of the multiplex tubes.

I was wondering if there is any additional information out there on this stereo (like service manuals or what not or an exact year time frame that this stereo had come out or may have been made, and how this fell in the Magnavox lineup at the time? I can't seem to fine a RadioMuseum page on this radio which is the oddest thing.

I appreciate your help.

The picture that is uploaded is a picture I snagged from an old eBay listing of the same model radio I have which actually has its remote speaker with it so you get an idea of what mine is supposed to look like, as I haven't gotten a chance to get a picture of mine yet.

I have two of those, one has the auxiliary speaker (also missing the little crest). Sams covered it in set number 737, folder number 6 dated February 1965.

SPKR may have been sold as an accessory. We had a Zenith mono console
and you could buy a matching amp / SPKR, the TT had a stereo cartridge.
MPX adaptors were common add ons but I have only seen a few.

OK, thanks for the info.

I have a question about this stereo, the FM band on this stereo for some reason tunes extremely broad like one station takes up the space of about .7 MHz on the tuning dial (for example one of the stronger stations in my area is at the frequency of 104.7 MHz on the FM Dial and that station on the tuner dial on this stereo spans from where about 104.3 should be on the dial to 105.1 would be on the dial), and the AFC function doesn't seem to be functional on the radio, not even in FM AFC mode, let alone in FM Stereo mode, because the tuner drifts like crazy especially in FM Stereo mode.

Would the aforementioned issue be the result of a poorly aligned FM IF Section in the stereo, I would assume the FM section would align similarly to the AM Section except that instead of 455 kHz for the AM Section it would be 10.7 MHz for the FM Section?
