Capacitors still cause problems. I made series circuit using 3 capacitors. Then I used 3 of those circuits parallel.
Unfortunately they still get too hot .
So I switched to 400 Volt mks capacitors. Those too get too hot. I found out on a forum that I need polypropylene types. Next week I will try to buy them. I hope the local store sells them.
In the meantime I will try to improve the quality of the signal at the drain. It does not look like a square wave.
Besides that at some voltages It seems to produce spurious signals. I had a look at other designs. Most of them load the drain with a RC series circuit. I Will try that too.
