Today I have made the layout ready of a super regulator based power supply, 230/115 VAC, +- anything out. Basic voltage is 15 volts but up to 24 volts seems to be possible. Output current at 15 volts is 200-300 mA but this is only a guess.
The size of the board is 137 x 102 mm, 5.4 x 4"
I have snubberized it. I'll guess this the first super regulator in the world which is snubberized. Over at some other forum there has been a hot debate wether adding a small resistor in series with decoupling caps is good and/or important. It's extremely rare in linear applications and I wonder if any high-end equipment has it. I'm pretty certain that I can't test it but at least the implention is good. I have this feature as a source of evaluation for the golden ears.
Even in the old days there has been snubbers, both the magazine Elektor had it in at least one design and also Mr. Ottala in 70's in his low TIM amp.

The super regulator pcb look like this in my Mac:
I'll guess the pcb will see the day of light in August or September. Right now it's summer and vacation.
If a few people want to be "beta builders" with free*) pcb's drop me a note. Remember though that those people need to be very skilled in order to get the parts in the right spot and be able to do some troubleshooting.
*) under certain conditions.
