Nakamichi 600 repair question


Looking for troubleshooting/repair info on a Nak 600 that when warm simply kicks out the play button and stops advancing the tape when about half to two-thirds of a tape has passed. Does anyone know if www.naks.com still has archives that can be accessed? It won't respond to my efforts and the guest page hasn't had posts for months. :-(

I would agree with atmasphere, rubber parts. Here's a link to the type 1 on Hifiengine, they also have the type 2.

Willy Herman for service on the west coast, did my DR-2 but really busy now.

@misterbobman This symptom is typical of the tires used in the deck becoming perished and so don't have the traction they should. Eventually the take up spindle can't handle the load presented by the cassette and so stops turning. When that happens the auto-shut off kicks in.

I recommend that all the rubber parts be replaced by a qualified technician. Sometimes you can find kits on ebay that have all you need. In other cases, Russell Industries on the east coast does have tires that fit (which is how I serviced out a Nak 700) but you have to figure out the sizes needed. I suspect that anyone competent servicing tape machines these days knows about Russell Industried but you never know. Here's the link:

belts, pulleys and tires for turntables and tape machines.

Have you seen this Service Manual? file:///C:/Users/Admin/Downloads/Nakamichi-600-Service-Manual.pdf

I'll second the Jeff Galin at Electronic Service Labs recommendation.He is "Mr. Nakamichi." And a nice guy as well!

Good luck with your repair.
