Oh, that makes sense lol well thanks for that, I feel like I missed the obvious and I'm a little frustrated with this project but that's why I joined this site, to learn. I've been cleaning the switches and I'll put it back together to see if all this cleaning is going to make a difference in the sound.

I just put my boombox back together and the cassette sounds a lot better! The equalizer lights are working in cassette mode and it has a bigger sound to it now, thanks for the help everyone!! You're all awesome!

Here you go everyone! My hand might have been on the mic for a bit but it does sound better! \m/

Does anyone know how to adjust the cassette speed on this model? Someone said there is a pot, but where?
Thanks!

There should be a hole on the back of the motor.
And yes DO NOT adjust the heads or anything unless you know exactly what are you doing or have a way to put it exactly back where it was before. All heads need to be readjusted upon the replacement only.

Thanks! I have replaced the belts, but still plays slow! I read about adjusting the speed, and I see there is a rubber flap in the back of the motor. Can't see a slot in there, but it is hard to see inside. I will attempt this as a final try before seeking professional repairs.

Yes that is it! I stick pre-recorded on quartz-calibrated deck 4 KHz cassette and adjust the motor by measuring the frequency on the line output. Make sure the flywheel shaft in the brass bearing lubricant did not turn rock-solid.

Thanks! I never thought about the motor lube! I bought this Panny about 3 weeks ago and it played fine. All of a sudden it slowed down a lot. I did replace the three belts, but did not think about the motor grease being bad. I couldn't imagine the motor speed would go out of adjustment that fast. Hopefully that is all it will need! I'll check it tomorrow!
Thanks again!

On Matsushita motor brass bearing I've seen it so solid that the motor shaft won't turn! A tiny drop of synthetic oil is a must on those! Most motors still keep the correct speed even 35+ years after being manufactured.
