I just started to refurbish my 1978 Rowe AMI MM-6 juke box. I am having a problem with the model 1100 mechanical unit. It will select records and deliver them to the player OK. When the needle approches the record the Mute relay should open up by closing the micro switch (cs5). I have found the switch and the cam it is on. I tryed to adjust the cam manually and everything is ok. but it goes back to the same wrong location on the next selection. Can anyone tell me how I can change the cam position perminantly. Thank You

Hello Bill,
Can you discribe your fault in a better manner, from what you said you had a ploblem with the operation of CS5 and the mute (you said you adjusted the cam, did you mean that you adjusted the switch position or that you adjusted the cam?).
I suggest that you read your manual and check all of the adjustments with regards to the tone arm, cam switches and gripper bow.
Regards

Alan,
I have only two books with this unit. They are the schematic & P/L for the MM-6 and the installation and routine service book. Neither of them say any thing about adjusting the cam I'm having problems with. I am attaching several pictures that may help explain my problem. The first is of the 1100 unit showing the switch/cam assembly on the left. The second is showing the switch/cam position when the record is just starting to play ( the black switch is CS-5). The 3rd picture shows the position after I manually rotate the came slightly clockwise. When the next selection comes to the play position the came is as in picture 2. I need to know how to permanently tweak the cam clockwise to release the mute relay.

The only documents I had was for the MM-6 upgrqade. I downloaded the Manual for the MM-5 unit. It was complete along with the manual for the 1100 mechanical unit. I am now able to repair and adjust the juck box to like new condition.
Thank you for reading about my problem and the solution.

The MM6 manuals were all supplements to the MM5. In other words, you need the MM5 and the MM6 manuals to repair this jukebox. The MM6 is just a restyled MM5. Both had two options for the sound system: 100% solid state amplifier or Transistor preamp box feeding a tube amplifier.

Hello Bill,
Any of the 1100 based jukebox manuals will do for the adjustments, the only difference in the 1100 mechanism is on the earlier mechanisms is that there was a double row of cam switches and the molex socket on the side of the mechanism was wired slightly different so care had to be taken when plugging into wiring to avoid a short.
Have a look at the two pawls on the casting on the transfer motor, the rivets can become loose and affect all of the adjustments on the cam in relation to the gripper bow adjustments.

The mm5 manual gave me the data I needed. I was able to adjust the cam and now everything is working normal. I believe my unit is 1978. It has a transistor preamp and a vacuum tube amp. The unit is working fine. Thank you everyone for your input.

Hello Bill,
The Rowe Ami MM-6 was produced in 1972.
Glad to hear that you have sorted out your issues with your mechanism.
