Ok, I'm stumped. It seems the flyback on connection 8 is what is pulling down the 340 volts. I feel like the flyback is good because I have plenty og high voltage.

In the power supply circuit, C3 SB a 25uf at 12 V. I had a 160V in there, and it shorted out. Today, I bought two 35 volt units. I put one in, and it exploded after about 40 seconds. Right now I have a 450V unit in there.


Here is the raster on my screen currently. The power supply and Hv section of my Sams are a couple of posts back, if someone could look and see possibly what may be wrong.

Thanks
