The hole in the resistor is 2.39mm +/-0.1mm so a Metric M2 screw would work. I used a 2-56 English screw and it fits fine.
Hi,
I have not seen the resistor heatsink tab yet.
If there is room I would drill it to 2.5mm diameter and flat the back on wet/dry 180 then 600. Use an M2.5 screw/bolt to fix to sink.

Just finished assembling one board.
Cant wait to hear what these sound like. I own a pair of twisted audio Rev C and I already think those sound great.

An externally hosted image should be here but it was not working when we last tested it.

Hurrah, hurrah Uriah,
today the package arrived.
Thank you very much for the nice work you have put into it!
I will see how far I will get this weekend. Problem is it is beautiful weather, something relatively rare in this country.
I have to enjoy that as well!
Cheers

I used these heatsink for TO-220
10 Units Heat Sinks Insulation Bushing And Film TO-220 - eBay (item 390201527722 end time Jun-26-10 05:13:33 PDT)
The Caddock is screwed onto the heatsink. The screw is a bit big for the hole but with a bit of sanding it fit.
The heatsink fits very well in the provided space
Transformer wires
This board has 3 ac inputs, AC1, AC2 ans PGND.
can I use a dual 24/25vac transformer, if I do what goes to PGND?
Or do I need to series wire a 12X12 and use the tie as png?

Your schematic is correct but secondaries value is wrong, you need 24V secondaries --> -24 0 +24V ---> 48V swing
I have 24vac secondaries if they are wired in series = 48vac, we want 24vac correc?
wired Parallel = 24vac more va correct?
Where does the PGND wire com from?
Can you draw a wiring diagram showing PGRD?
ppcblaster, your schematic is okay. Wire it as shown, like Dario confirmed you too.

Look at your trafo. Should have a picture like the one you showed us. Showing the colors for each position. Am I right?
Dont look right to me the blue and green should just be connected together and PGND should be connected to chassis/safety earth just my two cents...🙂
