1962 Motorola Console TV model 23SF15W-FMZ


This is quite a nice set. It features a 23" screen, a AM-FM-FM MPX stereo radio, and a Voice of Music record changer done up with the Motorola "M"s on it. Much like the RCA Nuvista set, this one was donated to the collection. I am happy to say that, with the exception of the rubber idler on the record changer, this set was in good working order upon acquisition. I did, however, spend some time cleaning up noisy control pots in both the audio and TV front panel controls.

The Chassis

This set uses three chassis: Radio chassis, FM MPX chassis, and the Television chassis. I'm not sure yet how Motorola does its chassis designations, but the Radio chassis is marked THS-1076B  6M62; the FM MPX chassis is marked HS 996-A; and the Television chassis is marked QETS-584A-05B  7M62. This set has a VHF tuner only, and intercarrier sound IF.

The V-M record changer has the features you would expect for a changer of the early 1960's. It will stack 14 seven-inch records, or 12 ten-inch records, or 10 twelve-inch records. Or, you can stack up to 10 records of varying size of the same speed, and the changer will automatically detect the record's size. The changer has four speeds: 16-2/3, 33-1/3, 45, and 78.

Eventually, an electronic restoration will be required. This TV is now my "daily driver" in the living room, and I have used the radio and record changer quite a bit. Eventually, the first thing to be replaced will be the idler wheel in the changer. In spite of the phono-no slip I applied to make the changer work, the wheel is still rock hard and somewhat noisy in operation. The capacitors used in this set are mostly ceramic types, but a few molded plastic caps lurk here and there. The filter caps will no doubt be the first caps to get replacement, even though there is no hum, why take chances?

Overall, cosmetically the cabinet is in good shape, with a few light scratches here and there. This will be a good TV to use for many years to come.
