Nearing prototype status. Less loop area in the regs part, check. Correct dimensions for even Mundorf SIO couplers, check. Poor man's C3 5mm cap alternative added, check. TP1, TP2 designations added (TP1 needs a pad of its own still). VR1 when turning clockwise there is more TP2 voltage, check. Sinks leg pads added, check. Gerberizes OK, check.

Can you post a pdf with actual 1:1 sizes so we could check with existing parts ?

Would it be possible to include pcb holes for fixing alternative heatsinhks like these ones ? V 6716Z - Spezial-Kühlkörper, 94x55x28mm, 3,6K - W bei reichelt elektronik

Some V+ input pads would also be welcome (if we decide to use external shunts... like v12 )

No because its not like the paradise that both Mosfets connect to same thing at their backs. Needs be discrete sinks. No need you develop shore eyes to check, its 5mm, 22mm, 40mm interstage cap pads. 46mm, 56mm, 66mm output cap pads. DC straight to phono pads are already there. Pad in the reg out/phono in star ground and red pads of force sense around. C2x can take a 5mm pitch connector even.

I know... I was planning to use isolator pads

Anyway... no problem as there is no gnd plane so I will drill the holes for the "common" heatsink.

Interstage cap will have to be floating (no space) but that is ok also because output cap will have to be placed outside the board (I like the "big blues")

Cool work

PS: heard in the radio that Greece is teaching all how to get up after the big euro crash... wondefull... pity Portugal waked up so late.

For using just parts anything the P2P approach is unbeatable. But this one gives a lot of slack for a board. The individual sinks dimensions take several 3.8C/W models which are enough. The Rset value will be fixed after test of temp in summer so there will be no danger for the less involved builder. No isolation=better dissipation and less wrong isolation builder's errors.

As for Greece and standing up stuff we have heard a lot of hype 3 yrs now, its seeing first for believing.
