For CM, is it okay to go higher than 22000uF to get a better capacitor (lower ESR, higher ripple rating, 105 celcius rated, etc.)?
I plan to use inrush current limiting. Would there be any problem with 33000 or 47000uF cap for CM?
I think that it may become unnecessarily rough on the diodes creating sharper rectification peaks (producing noise). Too much anyway for a steady current draw that will surely be below 1A and is already well covered with the smaller capacitor values. Unless when planning a central raw PSU for feeding several regulators all configured as DC input only. There it could be a big CLC even. So to have a rich quantity well filtered main distribution reservoir.
Salas I'm using the Reflextor-D to power Twisted Pear Buffalo III DAC, the requirements are 5,25-5,5VDC 440mA, my setup is 9V 30VA R-Core, R1 2R//1R5 = 0R86, the current is set to 698mA, the voltage is set with two green LEDs + 100R for RX, I used 12R as dummy load, the voltage across the dummy load is 5.290+
VDC.
Is the reg. working at the current edge?
Can I change RX 100R for 500R or 1K trimmer to set the Vout to 5,5 VDC?
It's possible that voltage drops

Its not on the current edge with that dummy. Its going to send 460mA on 12 Ohm for 5.5V so you may try rise Vout to that level.
Conventional trimmer has many ppm. I would use the trimmer to find the correct value after warmed up (also watching not to start cold at some dangerous Vout) and then substitute a low ppm resistor.
OK I use the trimmer to adjust the value, I adjust the trimmer to 100R to start the maesurement.

Salas with 1 K trimmer connected to the BIII max Vout is 1,089 VDC
There is something strange with the BIII could you please follow this link of TP support forum DC offset playing DSD files- Page 5

The trimmer is for RX in the Vref not between the Ref-D and the buffalo. I don't know the BIII switches. It must have a max current draw spec. If your CCS is set above that it owes to stay at the voltage output you set. I think they used it in this thread before with BIII successfully? Set at a safe Vo with dummy, then stick the mA meter in between PSU & DAC to see if it draws much more than expected. The reading will go to the CCS limit if so.
Russ White of TP said: "OK just keep in mind 12R at 5.25 V is only about 437ma. I think you are just running your supply out of current."
But my Reflektor the current is set to 600mA!!!!

First Ref-D I hear about not recovering from a fault. The current limiter usually saves it. Find what semiconductor burned or which Vref component is not touching well and change it. It will come alive again.
