VM
So did VM manuacture the "Micromatic" for Magnavox? It is a totally different mechanism than the standard VM that you saw on multitudes of various brands of stereo.
The first photo is of the newer micromatic (late sixties) and the second the earlier version from the early sixties.) The last photo is of the typical VM unit.
To the best of my knowledge VM never produced a unit with tome arm sensing. If you look on the VM picture, you will see the trip between the overarm base and the tone arm base. This sensed for 12" (LP) records. On the changer platform right in from of the metal trip is a small "button" that popped up and measured for 10" records. If neither sensor contacted vinyl, then the tonarm moved to the 7" position by default for 45 rpm records.
The last picture shows the VM produced Cobra-matic with the typical VM trip and sensing button.
Mostr manufacturers either used the VM's outright, or put their own style of overarm and/or tonearm, overarm and knobs onto the standard base mechanism. For example some of you may remember Zenith's Cobramatic. The used a tonearm with the head somewhat resembling a snake. But the main unit was straight Voice of Music.
I have never seen a VM on a Magnavox, although this may have been done prior to 1962 which is the earliest I personally have seen the Micromatic changer, but very well could have utilized before then.
But it is possible that Magnavox contracted VM to produce a changer that was propietarily unique to Magnavox.
