I had asked here for comments regarding modifying an old Lab 80, and basically it was suggested that I not do it. However the thing was free, and not a high end "collectable" model, so I think I will do it anyways, hopefully creating a fun , manual garrard Lab 80, (no mechanicals, no electronics, just an on off switch and the speed selector)
The motor has three wires going to it. Red , Blue and Green.
The Green is a chassis ground, I assume the Red is AC positive, the Blue AcC negative.
Am I correct or will this be a shocking experience?
As usual, any and all help is appreciated.

You might be right, but I doubt it. Garrards typically connected the on/off switch in the middle of the motor, so those wires wouldn't corrrespond to mains. If there's a neon strobe light, one of those wires might be a 90V tapping using the motor as an autotransformer. There are various possibilities. I suspect that you haven't actually found the mains input to the motor.
Could you take a photograph of the underside?

Garrard Lab 80 con't
here's what's under the plinth of the Lab80. I guess I could just wire the motor to a switch directly as long as it is rated for 120V, 10 amps or something like that (don't know the voltage rating on the motor but it is a North American one)
attached is a sketch of the circuit as seen from below. Thanks to any and all...

Garrard Lab80 wiring....con't
so I took the plunge and just hooked up the wires. Red to +120V, blue to - (return), and green to ground. My god, this is what everyone means about these Garrard motors.... completely silent (ya it was spinning).
So the next step is a fuse, a good switch and remanufacturing the idler wheel..

Hi,
I just took a chance, and bought one cheap from ebay. I also got a good deal on a rb250, so I am going to see if I can mount it. The seller said it probably needs a new idler wheel, so I am going to look for a place that refurbs them.

You may try the turntable factory
Although I have never seen any of his work, He has posted here and at other sites regarding the work he does. He also was kind enough to send me a very prompt personal email response to a question that I had, and I can only imagine how good his customer service is. I have to believe that this is the basis for his business If his customer testimonials (provided on his website) are even remotely true (and I have no reason to believe that not to be the case---anyone here have personal experinces?) his customers must be very happy.

They look like the place to send for a complete refurb.
I have this delusion of refurbing it myself. I have found a few places on the net that say they can repair old idlers, have to pick one of them, and send it out.
