My 975 cassette players play fast on the high setting and even faster on the normal speed! Would really like to correct this. Any ideas on how to fix it? I tried cleaning it while I was cleaning the tuner and volume controls. Both of those work excellent now, but cassettes still playing fast.

Also, there is a button marked SPEED next to the Mic and Phone jacks. It is used for high speed tape to tape recording / dubbing. It needs to be set to NORMAL.

I've tried both positions and both play fast and in normal it's even faster than the high position

OK, I would say it's not an adjustment, but a problem in the circuit of that high speed dubbing system. I wonder if you can bypass it all together

I don't see any pot after the norm/high switch. The switch is just a push button. I have cleaned it already. Not super knowledgeable on these, but am I to assume the more voltage the cassette mechanism gets, the faster it plays? And vice versa? Could I wire in a pot right before the cassette to lower the voltage and slow down the motor to play normal?

There is pot I just can't remember exactly where it is 🤔. Post some clear pics of the boards so I don't have to open mine
