The voltage doubling idea has worked out ,i changed this circuit for the 800 volts .
Forgot to add the positive negative on the end cap chain positive to ground and or towards ground direction negative out top
The output voltage is giving a touch more than what 4 caps at 450 volts are rated at might have to add another seems fine but better add another .
Its seemed i needed 8 1000 volt diodes here just really add 2 caps and changed the diodes around a bit i was using for the bridge rectifier i tried a few hours ago so have the PMT and CRT negative voltages are some thing i can work with ,1600 for the CRTs is doable .
I found the 2 caps on the AC transformer hold there charge on switching off ..would they work and discharge with some resistors across them ?
