OK, that's not too important. Most of the 5V heater windings I've seen have not been center-tapped. What are you doing with the rectifiers - two parallel tubes on each leg of the HV winding? Maybe you could post a sketch.

Hi TK, I copied the schematic from the post on July 12, in this section. It is under the title "what is the best way to hook up 2 rectifiers" and under sub section "tom I am not sure what you mean by that".
OK, I see that what you're doing is identical to the Scott, other than the CT for the filament winding and parallel filaments. There's no problem paralleling the anodes within a single envelope. You don't need balancing resistors, they'll just degrade supply dynamics. If it were me, I'd consider copying the Scott schematic in terms of the 30 ohm resistor and first two filter caps. Increasing the second cap to 40uF or so might be beneficial, but only if the power supply sags on extended low-frequency passages.
