Can anyone tell me if changing a belt can peoduce an annoying hum from the player during tape play? I changed out a 6.1" square belt to a 6" round belt and the player has a higher humming sound. What's that about??
Some amount of extra tightness from a belt creates extra resistance to the motor's rotation. This can create the humming sound but also check the starting capacitor connected to the motor which can fail. If you hear crackling as well, it can be a dirty motor armature where you have to clean off the carbon deposits between the windings gaps. This requires opening the motor which is not always the easiest thing to do.You have to be very careful that you do not damage the delicate carbon brushes.
Sorry, I haven't used this camera for a while and the blurring wasn't expected. Unlike these vintage audio pieces, today's electronics aren't built, or intended, to last.
