Rookie here, I have Glentek circa 1980, analog 90 volt servo amps with tacho

is it a good Idea to keep the tachometer feedback, what new amps

I was hoping to go to the CNC Workshop to attend and video tape your seminar on

Do you know if there is a way I can attend this without paying the $150.00, I

still saw a twitch on the Z at the same time as the X twitched.
