I built this socket from 12mm thick Teflon round rod. Screws are M3 stainless.
The purpose is to have a strong, stable, accurate and well insulated test socket.
I needed something able to resist to temperature and voltage, above all the socket have to keep locked the tube even in vertical position with no yielding.
