I have a question to the tubers out there. What determines the Anode voltage
rating on a tube ?? For instance ....I have a amp with 3-500z in it.... the
space between the anode and grid wire cage is very small ...Yet is has a
high rating for maximum plate volts..... My SB-200 with 572B has a huge
space between the plate to grid....But it has a much less voltage rating of
2750 V ...I know current and anode dissipation play into this. But could the
572 B's run on higher voltage as long as the total plate dissipation is in
spec ?? because with all that space it looks like there would be no flash
over problems or is there more to it ???
thanks John,
