10 ohms DCR!!!!!!!!!!!!!!!!!!!!!!!!!

With all due respect, Jeff, those Triad C-40X chokes have a DCR of 10 ohms. Wouldn't we be better using the Signal Transformer units that you mentioned earlier? The CH-1, while less than 1/3 the inductance (100mH vs. 320mH)it has only 1.5 ohm DCR.

Both of these inductors were intended for low voltage supplies. Using them at the AC voltages we're talking about worries me a little. Not for safety reasons necessarily, I'm just worried that the chokes will easily saturate even when run well under their maximum DC current rating. They are subject to MUCH higher AC flux in this application. VERY generously over rating them in terms of DC current might prevent saturation. OTOH, maybe you like the sound of the supply with saturating chokes ... :)

Also, if anyone is interested in 'tuning' the supply to achieve the 'flywheel' effect (as described by Henry,) it seems to be easier with lower inductance, depending on the PT.
