The console is model number 1SR276-F. The amplifier is marked AMP 175-55 which is Sams #448-9.
The tuner has "RO 55 02 00" stamped on it, which doesn't match anything in Sams, Rider's or Beitman's. Magnavox tuner chassis numbers all seem to start with "CR-" but nothing like that here.
I can provide tube numbers and pictures if it would help. Anybody out there have any ideas?
Thanks, Mark
I think Riders conked out in the '50s.
You say this is a stereo AM/FM/Phono. In my mind, that puts it in the '60s or later.

:I just aquired a Magnavox stereo console AM/FM/Phono and am having trouble finding service info for the tuner.

Mark, you probably can get buy with SAMS 441-9. Magnavox just didn't make the documentation on all models available for some reason. You got 10 or 11 tubes. I have had a 55-something and had same problem. I have a 54-01-BA same problem. But similiar schematics will do for the most part. After the 4th of Jul I plan to work on a model 1ST606; the amp data I got, will have to use a similiar schematic for the tuner because no SAMS on exact number. I have three other tube sets and a 1965 solid state.

Thanks for the info, I will try that Sams. I was looking in the Beitman's index & found a schematic for model 55-01 in the 1960 volume, page 70. This looks almost exactly like mine, except it has an audio output stage. So it looks like mine is a variation in that, right down to tube line-up & placement. Looked up 5501 @ Sams website & sure enough it spits out 441-9.

:Edd, Thanks for the schematic & info. A Magnavox AM FM Phono just followed me home. Took it primarily for the 15" speaker, but after playing with it, am having second thoughts. The guy was playing it when he gave it to me, and it does real well on AM. Do you know what the chassis on the bottom is? See

:I unplugged it, and the set seems to play the same. Have not chased all the wiring to it yet. The tube I pulled is a 6V6, so it's probably some kind of aux amp.
:Changer appears to be a later VM, but only two wires to the cartridge, so apparently mono. Thanks, Rick

:Hello, I'm new to this and this thread has come at a very convenient time. I picked up a Magnavox console and the tuner/pre-amp chassis is a 5924-00. Thhere was no results for that on Sam's. The general layout seems simmilar to the schematic Edd put up, although I haven't really looked mine very closely. Do you think they are similar enough to use the schematic as a guide? Thanks.

:Mornin' Bill and Edd, After vacuuming and brushing the following info is apparent:
:Upper "Tuner/amp" chassis is ink stamped RO 55 01 10
:Lower chassis is ink stamped 169-BB
:tubes in lower chassis are: 5Y3, 6V6(2) and 6AN8
:small panel behind lower chassis is ink stamped T-14 700717-1 die stamped 635974-2
:Phono is stereo, 3wires from cartridge and two coax leads to upper chassis, panel switch positions are: stereo, phono,fm,am, and tape
:Looks like small panel may be some kind of mixer/balance control for input to lower chassis
:I'm gonna study the schematic Edd posted and see how it compares. Tube complement is the same.

::::And yes, its a mono unit..not stee...roooooow.
::::Plus your power amp unit antedates the referenced Mag schematic in the AF output tubes, in the respect of that unit using 6V6's, vice the depicted miniature 6AQ5's.
::::Also the shiny galvanized metal ? / alumininiyum-yum ? plate on the bottom looks a little foreign to me.

:::::Edd, Thanks for the schematic & info. A Magnavox AM FM Phono just followed me home. Took it primarily for the 15" speaker, but after playing with it, am having second thoughts. The guy was playing it when he gave it to me, and it does real well on AM. Do you know what the chassis on the bottom is? See

:::::I unplugged it, and the set seems to play the same. Have not chased all the wiring to it yet. The tube I pulled is a 6V6, so it's probably some kind of aux amp.
:::::Changer appears to be a later VM, but only two wires to the cartridge, so apparently mono. Thanks, Rick
:::::
::::::Wow, the schematics are indeed GREEEEEEAAAAATTTTTTT! Thanks for getting them up so fast. Now I can get that puppy aligned once I replace the 6BZ6 AM RF amp tube (the only one that tests bad, merit OK, but high readings on the leakage tests on EICO 666)

:::::::Submitted as two parts...... the vital circuitry / schema info and a secondary suplement of the alignment data....since that little unit should really purrrrr on AM, what with its separate and fully tuned front end RF stage.

:That chassis unit which you mention, is probably one step down and a unit which was also possibly shared as a complement with TeeWee combo units.
:Run a tube comparison, and this probably will be the same or an almost identical unit.
:This supplied tech info is referenced as the tuner, the power supply / amp...and its variants...and the alignment info for the tuner.
:
:Note... that your units AM section is with out a RF amp stage......ergo.......you probably won't be able to position yourself atop a sand
:dune in the middle of the Mojave desert and listen to Noo Yawk Citee Aye Emm radio stations at night.

::Mornin' Bill and Edd, After vacuuming and brushing the following info is apparent:
::Upper "Tuner/amp" chassis is ink stamped RO 55 01 10
::Lower chassis is ink stamped 169-BB
::tubes in lower chassis are: 5Y3, 6V6(2) and 6AN8
::small panel behind lower chassis is ink stamped T-14 700717-1 die stamped 635974-2
::Phono is stereo, 3wires from cartridge and two coax leads to upper chassis, panel switch positions are: stereo, phono,fm,am, and tape
::Looks like small panel may be some kind of mixer/balance control for input to lower chassis
::I'm gonna study the schematic Edd posted and see how it compares. Tube complement is the same.

:::Hi rickd,
:::Look for numbers on your tuner. They could begin with 51, may even start with 55. The unit on the bottom should have some identifying marks too. That thing might be a Hammond product. Look for AO numbers.

::::Edd, The guy needed the room and after looking at the speaker, I agreed to haul it home. The "upper" chassis in this set uses exactly the 11 tubes shown in the schematic you originally posted. It sounds great. This is all with the "lower" chassis unplugged and cold. It's not doing anything. Plugged in, the tubes light up, but no change in the sound. Gonna have to look a little more closely tomorrow.

Do you know what kind of stylus cartridge is needed for this model, i have this model, but has no cartridge, and the manual doesn't say what kind other than "use like needles".
