Hi.
More news.
I found a trace in the printed circuit, open, at point A.
I put a 24 V lamp on the transistor collector and got the following measurements, and now the transistor doesn’t burn, but I don’t have any trace, or point on the CRT.
Are the tensions correct?
Do I have to turn off the points X and Y to see the point?
How can I measure the HT?

Many thanks.
Regards
