If I understand correctly, it sounds like the bass (first 32 notes) driver board may be blown. If the mid range (next 16 notes) is missing on just a few notes, it might just be burned out solenoids. Unplug those solenoid notes from the driver board and test them for continuinty for starters. If the solenoids seem, ok, then the mid driver board may also be defective.

If you determine that the driver boards need repairing or replacing, you can send them to Bob Baker for repair/replacement. Contact him at elecorch@aol.com and explain what you need, etc.

You also need to look around in there and see why this damage has occured. There may be a short somewhere. Make sure all wiring is in good shape, and properly secured. The boards should be free of debris, especially any metal shavings, spider webs, etc..

Cassette repair. Go to Tower records and buy a 15 count box of Maxell UR regular 90 minute tapes for ten bucks. Open the Pianocorder cassettes and replace the springs and pad using one from the Maxell cassette, check the two side rollers, replace if they are stuck. If the original Pianocorder cassettes are otherwise problematic, binding etc., just remove the the two reels with the tape and drop it into a Maxell shell.
