I have a simple question guys, after been reading for a while about power supply design for tube amplifiers I figure that must of the time for home use as "high fidelity" they use larger caps but for guitar power supply they use smaller size because of the sound they prefer to hear, I spend a couple of weeks designing this power supply I mean weeks because every time I read from other sources new ideas and recommendation keep updating the schematic, here is the question I know that the first capacitor should no larger than 100uF because of the stress of the transformer having larger numbers like 680uF or 1000uF caps, will act as a short in my opinion I might be wrong , so how larger the second cap can be? I was thinking that 680uF should be fine because I will use a choke but I'm not sure how large the choke can be too, I will leave the details here of how I want the mono block audio amplifier "not for guitar" home use only
the power supply is an Edcor part number XPWR247
660V (330 - 0 - 330) 325 mA / 6.3V @4A / 6.3 @4A / 5V @4A / 5V @4A
the configuration will be in Ultra Linear
from a Williamson schematic
the caps are placed in series to have enough room for voltage that is why I have a larger number caps in series "cut in half their value"
other question, I already simulate on PSU Designer II but I'm sure if I'm doing it correctly how large the choke can be for this application ?
