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.
