Hi Tina

I think I solved the problem. Voltage from the power supply was too high for the tube ( because I didn,t buy new for 60watt tube, I'm using the same power for the 80w tube) and I put it down to 24kv like it should be for the tube and now it is working ok, only the test hole that is fired for the test looks a bit bigger than I think it should be. So my father is now making another regulating device (we think better ) so the hole will be smaler and than i'm good i guess.

If there is something else that i should know please tell me.
Thank You for you're help.

Best wishes
