I have a 1975 10EE that blew the 22060 tube. I ordered and received a new tube from Monarch ($500.00+). Installed it today. Did not solve the problem lathe is not running. I called Monarch and they won't be back until Wednesday. I have a good friend who said to s-can the 70 year old technology and install a 3phase motor with VFD. This guy is no amateur. He has installed VFDs on two of my mills and knows electronics. I'm thinking that's the way to go. What say ye? If I go that way: 1. What horsepower motor? 2. Will I get the same performance from my 10EE? 3. Any salvage value from the parts removed; DC motor, Thyratron tubes, etc.? I love my 10EE and want it to be well again. Any comments greatly appreciated.
