As in any of our heapdone amp projects, you can use any regulators for the main amp which are 78xx / 79xx pin-compatible (TO220).
Almost all of our projects are supplied with discrete regulators of different sorts.
Voltage to suit that particular amp.

The 78Lxx / 79Lxx are for the SHPP.
We recommend same voltage as the main amp.

Fuse depends on power consumption.
Suppose you use a +/-24V UTHAiM with 22Vrms Talema.
And let's say you want to bias at 180mA.
And mains is 115Vac
Total power = 2 x 2 x 22 x 1.414 x0.18 = 23W.
Mains current = 0.2A.

I would then use a fuse of say 0.4A slow blow.

Patrick, forgot to tell you the board arrived the other day, very nice indeed. I like that the regs can be plugged directly to the PCB.

Is there a component suggestion for the aux PSU's? I haven't checked the other threads for this sorry
