HI
with 36VA the 63v caps are not too low ? I like 63v parts...

Nick your great build , with separate box, we use two psu caps one x box ...you use the resistor for pgreco filter or just the wire..

thanks

63VDC parts will be fine.

Just the wire.

Can I use this diode VISHAY GENERAL SEMICONDUCTOR|1N5399-E3/54|STANDARD DIODE, 1.5A, 1KV, DO | element14 Malaysia instead of MUR120?
It seems can support higher current and faster as compare to MUR120.

Capacitor position C301, 201, 101 is same as C302, 202, 101. Is that to be fill by either a film 4.7-10uf MKT or a 220uf electrolytic cap? And not both? It is the same as position C103, 203, 303 and C104, 204, 304.

Any diode meeting the power needs will work in the bridges. Your intuition/choice. MUR are well accepted by diyers and easy to find, thus they got proposed.

Those capacitors choices are explained thoroughly in the guide. Those near the output better be MKT plus R107,207,307 1R. 47uF polar caps and that resistor position be a jumper are reserved to battle oscillation if it rarely happens a bad interface to reactive load situation.

The C101,102 etc. Its better the 220uF polar if the application is a high gain or other noise sensitive situation. Else, just an MKT since it normally presents a more open tone. Some had used the polar, and bypassed it underneath with a small MKP.

I have ready the regs for +7Vout & -3Vout to feed the Jim Hagerman Piccolo phono headamp that draws 6Vdc to 24Vdc @15mA, how many current have I to adjust? 100mA seems to be very reasonable for the Piccolo, right?

Right, but adjust 150mA for the reg to be warmer.
