Don't know if these will give you any advantage but 6A10-T s are 1000V
PIV @ 6amp (but expensive). I almost doubled the diode "headroom" for my
latest GS35b but still use 1N5408s - 8 per string for 32 total for my
full-wave bridge. My transformer AC output is +- 3000VAC & (obviously)
anode at rest is between 4300- 4450VDC based on mains voltage, no problems
so far. No resistors or caps across them of course- I won't delve into that
argument - suffice to say that if you are worried about variance buy them
"taped." I assume those are processed consecutively & thus minimum
variation. Works for me.
