If that doesn't work try Northwest Audio in Seattle WA,
ask for John.His specialty is restoring Teac reel to reel
tape recorders.He totally restored my 4010Sl Teac.Last time I was at his shop he had a ton of Teac recorders all over the place.He must have had 20 to 30 machines lying around.I'm not sure if their all being serviced or just spare parts.
