Hi David,
I should try to use all caps in the "suburban" of the LOPT with 1000 VDC.
Even the caps at the vertical output will work fine forever with 1000 VDC.
If a lower voltage is given on the original caps, you are fine with 630 VDC.

With the worse cap market of today, it is a luxury to place 1000 VDC caps all over.

Please realize, that during the warm-up the valves don´t take power, but the
valveless power supply offers a higher voltage (not regulated).

Regards,
German Dalek

P.S. Thanks to call me MARC, but I am still alive and was never a musician.
