If there's too much slack in the belts it will cause the auto stop to malfunction.
Also check the rubber parts wherever you can to make sure the hard rubber parts are hard and the soft rubber parts are pliable .

I used to have an immaculate trk 8190 . I loved that boombox . I still want to kick myself for selling it.

Sounds like an issue with the Clutch. When it reaches the end of the tape the clutch should slip to allow the mechanism to complete the Mechanical logic.

I have been known to cut the spring in half to reduce the pressure plate tension. PS its just the take up reel, doesn't affect tape tension as it controlled by pinch roller.

Old Nationals are actually adjustable.

Old Nationals are actually adjustable.

Can you explain, how do you adjust the clutch in a National?

There is a brass plate that can ratchet the tension on the take up reel.
