159M: 15H 100mA 256ohms 500V
The 100mA (as opposed to the 150mA of the 157Q) looks okay for the B+ of the pre and phase splitter tubes, but will I need to adjust the value of the Caps of the PI filter in which the choke is used?
About those filter caps in the PS, particularly int he Pi philter...what voltage rating should they be?
No, you don't have to adjust any capacitor values for the different choke.
The power supply makes almost 600 volts during warm up and then settles to ~535 volts, so any caps you use must be able to handle at least 600 volts. All the caps are 450 volts, in series the way they are, that gives them 900 volt rating.
I am about to start building another one and will arrange the filter caps very differently. I will keep everyone posted as to what I decide. The rule here is: more is more.
