MPX means multiplex. This is the (analog) FM stereo broadcast system used to this day.

The FMS-413U is in Sams 645-7, which is 1963. Pretty sure I don't have that one...

I have acquired a Zenith MJ-1035 since this thread started, and I'm unhappy to report that it has series heaters and is NOT isolated from the power line! There is a version with 6V tubes, but it is also NOT isolated - it has only a filament transformer. How much more would it have cost to add a plate winding to that transformer? And to think that I ran it with a CD player plugged in... never again!

Tom, I also have an MJ-1035 and was thinking of connecting my solid-state Radio Shack SCT-11 cassette deck to it. After reading your reply to this thread, however, I've decided against it for safety reasons. (My MJ-1035 is like yours; series-string tube filaments and an unmistakable warning on the back cover, stating that the chassis is connected directly to one side of the AC line--I don't want to think of what might happen :eek: if I were to connect my SS tape deck to it.)

The external phono inputs on hot-chassis Zeniths I have seen connect the shield of the phono jack to the hot chassis with an isolation capacitor for a measure of safety, however I still would be very careful. There can be enough of a voltage difference between a truly grounded device and the phono jack shield to cause a shock if both were touched. Also there seems to be a lot of hum problems when trying to use the phono input with external equipment.

One of my neighbors found this Delmonico-Nivico AM/FM/Phono Consolette on the garbage, it was in great shape and works perfectly. It has 8 tubes total. It has 4 speakers and plays pretty loud, getting 2w per channel from a pair of 50c5 tubes. I wish I had found this one!

EDIT: Is this the one in question?

The radio and speaker look just like the ones I have (no cart though). I did NOT see the MJ1035 number on the back though. Is that a chassis number?

My MJ1035 does show the model number (MJ1035-1), stamped on the back cover. The chassis number is 11J01.

X347W? Hmmm. :scratch2: I've seen pix of those radios here on AK (I think AK member kg4cna, Allen Scofield, has one, as he shows a picture of such in his avatar), but to the best of my knowledge it's not stereo. I saw the pic of yours, however, and it definitely looks like an MJ1035.

The MJ-1035 was one of Zenith's first attempts at designing and marketing an FM stereo radio for home use (the company first introduced it in 1961 and came out with a 12-tube version, the MJ-1035W1, a few years later); for monophonic FM the reception is good in urban to near-suburban areas, but apparently the stereo reception beyond about 15 miles (read far-suburban and beyond) leaves a lot to be desired. I saw a post about the MJ1035 on the Antique Radios site (www.antiqueradios.com) the other day which addressed this problem (if one can call it a problem), but did not mention that it can be worked around by the use of an external FM antenna as opposed to the line-cord antenna. (Even a cheap pair of TV rabbit ears will probably work better in all but fringe areas than the line-cord antenna.) I live some 35 miles east of most Cleveland FM stations and can hear every one of them (in mono) very well on my MJ1035, just using the built-in antenna. Haven't tried the phono inputs yet, though, although at first I was toying with the idea of connecting my solid-state Radio Shack SCT11 tape deck to them....until I recently saw a post from Chad Hauris stating (in paraphrase) that there is a risk of shock if the blocking capacitor fails (in most of these radios in use today the capacitor probably failed years ago), and a grounded device is connected to the jacks.

Last time I was down at Terry's, he was telling me that there was a big row back in the days when FM took off-that lots of mfgers apparently purposely de-sensitised the FM sections on their radios...Why, I don't know.

I just picked one of these up at goodwill. A bit of tuner cleaner and WD40 and she's running just like new.The mechanics on the turntable are classic. Very good sound. And yes, quite loud. I hooked up a Utah AS-2 to the external speaker terminals (which switches all four built in speakers to the right channel and the external speaker becomes the left channel) It really rocks...too funny, I just had to laugh. I love this little guy.

Spec's :
Principle : Superhet with RF-stage; IF-Freq. 455/10700 kHz
Wave bands : Broadcast (BC) and FM.
Details : Changer (Record changer)
Power type and voltage : Alternating Current supply (AC) / 110 - 120 Volt
Loudspeaker/pwr.out : 4 Loudspeakers
Model: 1125U Material Wooden case
Shape : Console, Highboy (legs > 50 %).
Valves / Tubes 11: 12DT8
