today I finally tried to testfire my K40 rebuild.
I am using the Stock LPS and a brand new Cloudray 35-45W Tube.
Coolant is demineralised Water.
The Problem: tried to Testfire via Button, the AmpMeter never goes above 2-3mA, even with the pot set to full power. The Tube just creates a very small burn on paper placed at first mirror.
As the LPS is not new, is it possible that the LPS is the problem here? Or could it be more likely the tube?
Thanks a lot & best regards!
