Ok thanksWe discussed that before. A big transformer does no harm besides the possibility to couple more HF, RF into the circuit then a smaller one. Others claim that big transformers have more slam and grunt.
I will have to get rid of 30 Volts with an passive LCLCLC thing.
yikes.
I have shown it several times but for the new comers here it is again:
I use the Preregulator from my Opus Magnum Phono Stage.
Because Block does not have 2 x 24V transformers i use 2 x 2 x 12V per side where i put the windings in series. The diode bridges are IXIS Silicon Carbide snubbert with REL teflon caps. The 10.000uF caps are slit foils, today i would use Mundorf 4 pole. The common mode chokes are from Lundahl. Loaded, the supply puts out plus-minus 30V, the maximum i recommend for the Paradise R3.

Another question from the fool;
should'nt we do some Pre-reg Boards for the poor in Wallet and mind ?
Splendid Idea sometink like those?

I would probably build it P2P... no need for a pcb with such simple setup.
Joachim, why only a 100mH choke? I like these as an alternative to the prohibitively expensive Lundahls better.... Frag Jan zuerst- Ask Jan first: Roehren und mehr, the 10H 330R choke

Actually the original design had the Talemas BEFORE the diode bridges to get rid of the HF/RF noise from the transformer. They can be used though in a conventional CLC pi filter like you did simulate. A bigger inductance is even better, sure, but they are inexpensive so good for experimenting with this technology.
