Yeah, dshoaf can probably fabricate something out of thin wood or plastic sheets. Looking at my spare tone arm, the head shell is adjustable. Another thing, some automotive restoration parts places carry a plastic mold replication kit, for tail light lenses and such. It forms a clay mold around the old part and fill it with liquid plastic resin. You'll probably have the only clear red cart jig around, but maybe stick a light bulb in it. Think Eastwood Supply has these. Looked into the 1302 lamp and it's 6.3v @ .04a. If using an LED, you'll need to parallel something like a 200 ohm resistor across it to keep the speed control circuit happy.

Yer-isn't!
I have used that screw to adjust the cartridge position and as such the stylus directly over the tip of the platter spindle center.
John, What tool are you referring to? Do you have any measurements you can share?
Thanks,
Ron

That high voltage buzz
Yeah, that's the ticket! The Owner's Manual discusses its use but the little jig looks quite unique. It seems that there are a couple of critical measurments that need to be taken so that it can be used or, at least, a small jig of plastic could be fabricated.
Sloober, thanks for the heads-up on the bulb issues, too. That will save me some time. Sounds like there needs to be some specific current flow through them to be valid for the rest of the circuit. I'll check into the schematic in the tech manual to see what the relationships might be.
Nice to know others are in there with this 'table, too. Thanks for all the help.
Cheers,
David

The table came with a plastic tool that fits over the headshell. It has a small pin that fits into the underside of the arm where there is a small hole. It then has a small line that marks where the centerline with the spindle is. You slide the headshell forward or back to get the stylus tip in line with the mark. I was supremely lucky to find the tool inside my table (along with a shure M91E) when I first opened it up. I recently saw the tool on ebay...for over $100!
I was thinking of having mine cast to make more, but there is limited demand I'm sure. Without the tool, you could do the same thing with a laser level. I have one that projects a line for hanging pictures etc. If I set it on the platter, with it's notch centered on the spindle, and aligned square, the laser line should hit the diamond on the cart.
I will try to get a photo of the tool and post it. I left my camera at work. John
