This Harman Kardon CD91 Cassette Deck Plays Slow...Can I Fix It?

They make an electronic solvent cleaner. Spay on dries by itself. Degreasers and cleans gears, electronic parts.

Thanks for the tip! I have another cassette player that isn't working right. Maybe I'll pick some up before I tackle that one.
