How can I get my Sony Cassette-Corder WM-D3 repaired?

[jaco100]

Is there anywhere in the world where I can get this great Sony "Professional" WM-D3 Walkman repaired?

A beautiful, solid quality machine, bought in the US years ago, that still works, but which requires an overhaul. Electronics are completely OK, but mechanically it needs replacements for rollers with flats (I think) and adjustments to the tape cassette tray opening & closing mechanism.

Any suggestions will be much appreciated!

I have a Sony WM-D3 that needs to be repaired and I request information on a repair facility (ideally in the USA,if possible) to get it repaired. I am prepared to send it to a repair facility outside the USA, if necessay. Please reply.
