TSE capacitor question
Can't seem to find a mention on the forum - C6 in the schematic is 100uF, 350V; in the parts list it's 47uF, 450V.
Seems that 100uF/350V is correct, but can anyone verify this?

C6 is the filter input capacitor to the bias supply filter...

C6 in the schematic is 100uF, 350V
When the schematic was drawn 350 volts was enough since most amps used 45's 2A3's or 300B's at 350 volts or less.

Now we have 300B's and super 300B's, and even hot rodded 2A3's that will run at 400 volts or more. If you are building an amp that runs the B+ below 350 volts then use the 350 volt cap. If you are going to run a higher B+ then C6 must be rated for the higher voltage. Use the largest capacitance value that will fit the PC board at your chosen B+ voltage.
