Where is the closest area to buy a foot pedal for panasonic microcassette transcriber RR930

It sounds to me that you might have a mechanical problem in the machine. I am not familiar with this machine, but I have worked on lots of tape machines. The belts and rubber pieces can get slick or stretched causing problems.

Probably has a bad sensor belt (small belt attached to silver and black reflective wheel).

With the foot pedal connected, you need to push the play button on the unit. Then the pedal will operate.

check with a sony service center, or even better, call sony

If neither rewind nor backspace work, the common problem would be that the solenoid grease has dried up and the solenoid is not retracting all the way. However, the track that the mechanism moves in also wears out, as well as the plastic rocker that depresses the rewind button where it engages the metal slide.

If backspace works but not rewind from the pedal then the problem is the pedal.

There is a rubber drive belt that needs to be replaced, Panasonic part RDV101YA. This place says they have them:

I've never had to work on one of these so I can't say exactly what you might have to remove to get to the old belt and pulleys it rides on. But it's usually not too bad of a job to change a belt.

Sounds like a feed back, make sure the mike is off, otherwise it gives a high pitched sound.

If the foot pedal is pluged in, press the play button and then you should be able to activate it with the pedal.

This unit is driven by belts. I would suspect that the belts have dried up a bit and are slipping. Replacing the belts should resolve the problem.
