Why not use an arc'ed lathe?

'manufacturers like me'??

We've tried really hard to make our stuff plug and play; automated the bias, made it really easy to set up the amp (matched tubes not required) and such. I recognized 30 years ago that stuff has to be easy to use or it will wind up in a closet or worse.

'Manufacturers like me' have got nothing to do with it. If you want to give someone a hard time about it, talk to the lathe manufacturers? What's that?? you don't know any??

Sheesh.

@atmasphere : What I meaned in reality was not that you are the lathe manufacturer but you are an audio items manufacturer and in that post you speak as it not as a customer in that specific regards.

Sorry, no intention against you.

The idea died like square wheels.
