SSHV1 can give more than 100mA if you will lower its ref and leds resistor to go under 100V too.
Just installed the SSHV2 into the PSU for my Phono amp, my reaction is the same as Merlin, "WooooooooooooooooW", so many details and so clear, much wider sound stage!! Great job Salas.
Need to use a larger heatsink😀

GND layout, Schematic used for RIAA & pic
N.B. Pic not show wire connecting GND chassis Tx, black GND wire is RIAA GND, alone one green wire is GND SSHV2 jumped F0+S0 at the pcb, two green wires are GND input/output RCA

Oh my good😱 the shield isn't connected, I think that I have to connect the shield as follows:
RCA Input: not connect, RIAA input connect
RCA output: connected, RIAA ouput not connected
OK?
Or have I to connect the shield both sides?

You know how it goes with hum elimination on low signal high gain circuits. Nobody can solve it from afar better than the one who can put his hands on. Try different approaches so you can kill it all together if possible. See odd things also, like if your metal can capacitors react to grounding their shells for instance, but make sure there is no high voltage on those shells first. Too many things, takes patience especially without FFT, scope, strong troubleshooting know how.
Yes I know but I forgot to shield the low level signal and it's an important thing because I remember when I make your Simplisitic NJFET RIAA.
Thank you Salas for kind advice, I finished few minutes ago grounding the signal cable, I will test & rapport.
merlin, re do the solder joint on rca ,don't look so good, at last on pic.... ag without pb ?
My phono is Toccata MK II, A variation of the Arthur Loesch Preamp Design by Thorsten Loesch
Do check the dissipation requirements of the CCS mosFET and the regulating mosFET.
This is especially important the higher the input voltage to the Salas Style Regulator.

Any thoughts on the best caps (soundwise) for C1 and C2. Do you think it´s worth spending the extra for say Auricaps ?
A subjective area, depends on taste and synergy with the rest. Those caps can be influential as far as anecdotal feedback maintains in the course of this thread. I would just swap a couple of models already in my stash to determine if there can be picked up changing my system's tone, before allocating funds to that. Such caps you mention can easily demand more $ than building a couple of regs themselves.
