stopped last time it worked many years ago, rebuilt the amp & power supply, cleaned and cleaned up machine, The carriage was in the play position, it seemed it had just placed a recoud on the turn table and was ready to play when the power supply burned up' so I put a record on the turn table and it went ahead and played, but when it came to the cut off the gear jumped on the carriage drive gear and did not return the record to the magazine, I suppect the carriare gripper is froze up from many years of setting, how do I tell for sure? please help if You can! doc ellis |

Of course, with a machine this old you do have to take the gripper assembly completely apart to clean out the dried up greases, then oil and reassemble. http://flippers.com/Rockola-tips.html If you don't do this you will not have a chance of a properly working machine...

If the mechanism is too gummy to move easily heat the assembly up with a hair dryer (on medium to low) for a few minutes to soften the dried up grease/oil. Do not 'cook' the assembly so that it is too hot to touch!

You dont need a book , you need to oil that joint with light oil and
then some heat wont hurt . It may need taking apart if it wants to get stiff again . |
