Lubricant won't usually help. Make sure all the other components (other belts, perhaps even one to drive the counter, if it's mechanical) aren't worn or sticking. Clean the multipole record/play switch (usually at the end of a spring or rod on the main board). Spray with contact cleaner, put in a blank cassette, and go in and out of record mode numerous times. But if it was a sudden change, I suspect the motor itself. Check the motor speed control trimmer, usually hidden under a rubber seal on the back of the motor. It can become dirty or corroded over a long time. Turn it back & forth with a fine screwdriver, and return it to its original position. If the speed is now steady, you'll need to make sure the pitch has been restored before buttoning it up. If that doesn't help (and I suspect it won't from what you say), the motor itself may be gone. Many of them have an internal transistor/IC speed control, and this will die suddenly. Some develop bad contacts, if it's a typical little DC motor. These motors are cheap little devils, but will cost you some $20 or more to replace. Plus, getting it out is no small engineering job. :) Dennis _______________________________________________ Finale mailing list Finale@shsu.edu http://lists.shsu.edu/mailman/listinfo/finale
