Title: Rockola Max 477
Post by: MO Hillbilly on July 20, 2017, 12:20:01 am

Hi All:
Needing some advice on my Rockola 477.  It puts the record on the turntable, but will not reject.  It feels like the gripper motor has run out to its limit after the record is placed down on the turntable.  The record will not cancel with the cancel switch, nor the tone arm switch.  I've switched out the mech board, too, with no change.  If I manually take the record back to the magazine by manually spinning back to gripper motor, if will simply go back to the turntable after powering up.  I can't get beyond this problem.  Thanks for your ideas.

not 100% on this mechanism setup, but it sounds like a misadjusted or faulty switch (or wire).

I'm thinking it likely has a switch that senses when the arm is up or down positions. i have a feeling this is where your fault is going to be... either with the switch itself... it's adjustment... or the wires coming from it.

run the mechanism and watch how it goes. verify with a meter that switches are opening open and closed when they should.
