Trying to finish up ordering and upon looking for the choke value I see the BOM has 30hy/40ma but then in a more recent post I see 20hy/100ma. So; can anyone enlighten me? Thanks J.R.

T suggested going with the 20Hy/100mA over the 30Hy/40mA because of the current draw. I was planning on using Hammond's 193C. Below is the link I got this from. Look down until you see my post entitled "Hammond choke." Please follow thread and help me understand if I'm about to order the wrong item......Colin

Hey-Hey!!!,
The 20 Hy/100 mA Hammond 193C is a fine piece. We are about double critical current with 250 volts input. This also offers the additional current handling to change taps onthe PT and go fith a shunt regulated VR-tube power supply later.The Hammond is a litle less than half the price of the 8039 Heyboer choke at about $30 instead of $70 or so. It looks like you guys are in fine shape.
regards,
Douglas

Oh, the 'big one'. Nice choice. I am listening to mine right now. A super L in the L-C filter is a wonderful thing. Tell them what sort of endbells yo want. You can get them like the power Iron of a St-70 Dynaco, which requires a bigger and more troublesome hole in the chassis, or vertical. Critical curent for that one with even 500volts to the rectifiers is about 10 mA. I am taking 4x that much and the PS is showing .2 V of ripply. Just as PSUDii predicted. Nice to have a good Sim, that's for sure...
regards,
Douglas
