So i got a new quad now and.... nothing!
No HV sizzling ;-(. And no HV down LED.
So i hang my oskar on the HV Splitter and only got a few Peaks, no DC voltage. For a further testing i am still searching for a servicemanual to test some of the interesting points.
If anyone has a few tips, to isolate the problem i would be happy.
I already pulled out all of the tubes. What kind of waveform signal should the PJ have in front of the Quadropler?

So to give you a live feeling, the problem is solved.
I turned the supply a little bit and then the unit stared to work.
In the last 30minutes i resoldierd the Powersupply and the failure didn't appear again.
The PJ is actually in cycle run with full contrast.
The counter is on 17600h so mabe i should think about recaping? But what caps are driven very hard?
