Amp for Grampian C cutterhead?

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.

Can anyone point me toward a resource to find out what sort of power amp I should use? The search function's not doing much for me here.

Thanks!

I think the major thing is the impedance and whether it it is a feedback type Grampian.
I know we have been through this many many times before on Lathe trolls
If it is a low impedance non-feedback unit almost any power amp of 50-100 watts should be fine. Does not even have to be stereo.
If higher impedance or a feedback unit, other considerations apply, which have all been discussed here many times.
Look for threads on Grampian heads, cutting amps etc.
