Hey Douglas,

I've got 330mA on HV A/B triode strapped 6550 stereo amp. C-input. The choke calculates out to about 4H (B+, 500V) including the FE tubes. The proper sized L combines FE plus the % of B. Then another choke for the FE, around 60H, IIRC.
Adding an additional CL section helps kill the ripple and minimize the total capacitance, especially at C1, then C3 IMHE of course.
Just finished a 600mA DAC (LV obviously). The proper sized chokes are 600mH.
The above were built by Jack a while ago.
Choke input is a different beast altogether but we know that...

Cheers.
