The Rowe MM-6 was used in a jukebox rental
engagement at the
Crestview Baptist Church in Midland and was enjoyed as part of their

Update: 8/9/05. The MM-6 had been playing well at the shop for several months, however a strange problem cropped up recently. The machine would imediately reject some records, some would play for a few seconds and then reject, and some would play fine. There did not appear at first to be any pattern to which records would play and which wouldn't. I first suspected bad connections at the microswitch bank as that was a problem on an MM-4. I cleaned off the terminals on the switches with Deoxit and a contact burnishing tool, but this did not solve the problem,
Then I recalled back to a problem on the model "K" where the gripper motor was coasting due to the rotor not popping out of the armature when the power cut off, thus moving the mechanism forward when it was supposed to stop and this was triggering the reject cycle.This was fixed on the "K" by lubricating the rotor. I lubricated the gripper motor and geartrain on the MM-6 with S'OK! penetrating oil and this quieted up the mechanism but did not solve the problem.
I then looked at the records which were playing and the ones that were rejecting. It did not matter where they were placed in the magazine, only certain records would play. Comparing the records which played to the ones which rejected, those which worked were thicker. The problem was, that the thick records would hold the magnet far enough off the reed switch which trips the reject cycle, but the thin records were allowing the magnet to get too close too early in the record's play cycle.
Adjusting the magnet adjustment screw on the tonearm allowed proper reject operation.
