I wonder how it will compete against my XOno.

What is actually the input voltage the reguator want's to see? Probabely I can recycle my XOno PSU for that.

A minimum of 30VDC, more would be better with a maximum of 42VDC.
See 6.1 in http://en.wikipedia.org/wiki/42_(number)


Ooops my mistake, that was for the Pradise 1, for the Paradise 2 (running at 18V) it should be 24VDC minimum up to 35VDC maximum. For best performance an reasonabel disipation I would select 29VDC that is a 22VAC transformer, transformers from 20VAC up to 25VAC can be used.

Are you talking about the new Paradise working at 18V ?

Using 42Vin would create a 16Vdiff Vin-Vout this would need to be dissipated in heat right ?

At what point the cascoded CFP bootstrap CCS drops out? 1.4V > Vo break point? So people could know limits VS mains tolerances and trafos.

Hm... XOno PSU has 30VAC. This is to much.

As I have a Nagrad UPS in the pipe, I am going to use this. This does the trick, I think.

That will be a blast!

The CCS uses one Led as an reference and the CVS that feeds the CCS uses two Led's as an reference, that makes that optimum regulation is lost when the CVS looses it's headroom. If you give the CVS 2Vols headroom, then the minimum DC-in would be "DC-out + (2 * Led) + 2Volts headroom" = "18 + (2 * 1.7) + 2" = 23.2 to this we have to add the 'ripple-floor' of the raw-input-voltage (lets say 1Volt) and we get at "23.2 + 1" = 24.2Volts minimum input voltage (when using 1.7Volts drop on the Led).

Also having a load of BF245C will they be acceptable to sub J310 as the error amp's active load in the reg and in other places in the phono maybe? They would need some Irish dancer feet bend but they pay in noise figure.

Right. I thought they were mere diodes until I zoomed in the PDF.
