stamper playback system

This is where record cutters raise questions about cutting, and trade wisdom and experiment results. We love Scully, Neumann, Presto, & Rek-O-Kut lathes and Wilcox-Gay Recordios (among others). We are excited by the various modern pro and semi-pro systems, too, in production and development. We use strange, extinct disc-based dictation machines. And other stuff, too.

Ok, like I thought. Standard turntable. Tonearm mounted in standard location. Tonearm rest in standard location. Tonearm can swing out to accommodate the reversed direction of playback. Tonearm is straight. Headshell is crooked the opposite way than normal. Something like a 45 adapter for the center hole.

It is actually quite difficult to play a stamper even with this turntable. When you drop the needle for lack of a better word, it almost always lands in the land between the grooves. Which is odd sounding since the right and left channel are one revolution out of synch. You then need to gently tap it toward the center until you land on a groove.

One cool feature, the turntable has 2 magnet rings on the surface, to hold the stamper flat.

Wyndham Hodgson at Expert did make such styli, indeed, for awhile. He told me so. Sounds like he doesn't right now.

I can have them made two ways. One stone with a notch. Or, you can grind two tips, bond them togeter and set them onto the metal part of a standard playback stylus.
