[HomeBrew] Dual output power supply?

[n6kyr@netzero.net]

Hi All:
I need help for a power supply I'd like to build. The output I'd like to have will be around 400-600 VDC (about 90-100 mA) for the plate supply and 200-250 VDC (30 mA) for the screen supply. I found a 600 VCT, 250 mA xfmr from Hammond that I have on hand. The prospective circuit would be to use a full wave bridge the two outer windings and run it through a pi networked choke/2-cap filter. The center tap will not be grounded but instead, run through another choke and filter cap. I saw a similar circuit on building up a vintage transmitter. Does anyone have any design considerations or comments about doing this type of circuit? Thanks. Cal, N6KYR.
