Re: Post#23:
Hi Rob, multiply the 300 volts by 1.414, that will give the voltage across the HT electrolytics before the amplifier valves start conducting, that voltage turns out to be 300*1.414 which equals approx. 424 volts DC, that means the electrolytics should be rated to at least that voltage, so a rating of 450 volts DC would do.
