Thanks! I've redone 5 or 6 of these DRRI main filter caps. The last two I used two 80mfd/450VDC F&T (for C31 and C32) and replaced R65 & R66 with 220k-ohm, 1-watt resistors. The first few DRRI's got Sprague ATOM 100mfd/350VDC caps, with 220k-ohm resistors.

I asked about the 220mfd/500VDC cap replacing the 220mfd/100VDC because someone on the Fender Amp Board is redoing his amp's caps and wanted to use this higher voltage rated cap. I'm not sure what effect the voltage rating has on the GZ34, which sits next to it.

Thanks!
