Alex, what can I say
Your PCB's are truly a work of art. I'll print it off this morning and have a very close study of it all... thanks.

Hugh... it's great to see you back in action, hope all is going well.

Till now Gannagi, post 341 2 boards,
Dudaindc post 347 2 boards,
Mooly some boards?
Alex MM some boards?
Thread Starters?

Anyone else interested just post your interest and I guess we will go from there. It looks like Mooly is reworking his design to use a common psu, which is a good idea to keep costs down.
Please correct my name to Gannaji. Thank you for your efforts.

I've printed the board out to scale and find we're a bit tight on real estate. The high wattage resistors (the 0.22 ohm) and the PSU caps would be similar in size to the parts in the picture. The small resistor is a normal 0.5/0.6 watt metal film.

(I feel really terrible saying this after all the hard work Alex puts in on this because the boards are spectacular. Have I missed something here with the part sizes )

The board layout is good. All I would perhaps alter is the NFB takeoff point which can be done easily and maybe look splitting the grounds... at least to give the option. I'll look at that more.

Small Resistors (0.4in) and those 2-3W wirewounds should fit if legs are bent tight tight to body, my guess on biggest cap to fit would be 330uF 63V (3*330uF = +/- 1000uF)

That is where one is told NOT to bend the legs.

Iv'e been told
the default for 1/4W resistors on my software is also 0.4 in.
but I like to give warmer resistors some room to breathe, Im novice though.

Picture is how I fitted 5W on same situation on APEX SR200 3.1 board

Wow alex, that was real nice job you did. Better let the specialists comment on the layout as thats above my head, but from a visual point its beautiful and I can see from your design it will be easy to correctly populate the board.

Looks like we are a lot closer to getting some pcb made, appreciate the effort as I am sure everyone does.

I am out for a few days till end of week but when you guys are ready with some final files on an agreed upon layout by those with more technical knowledge than myself, I am happy to put in order for as originally proposed. I added Marco's interest post 354 to the list.
