I bought the "RC0050 051 8" for about $75 CAD. After shipping and tax it's about 100 dollars.

I got a mouser project finished up for the EHHA Rev A BJT version. 
 
If someone wants to go over the BOM and let me know if anything is missing, it would be appreciated. 
It is missing the heater transformer for sure which i will add later tomorrow.
 
I will also substitute parts for those items that are back ordered as well in the next update.

Got my boards yesterday.  Now just need to wait for Jake

One suggestion for the next board run: provide an indication of LED orientation on the board.  It's clear from the schematic what it should be but I don't see anything on the board itself (except for the arcs on one side being ever so slightly shorter).
 
Can't wait to get going.

Ah, nice that there is a picture posted. You guys have already figured this out, but the big hole in the rail supply section is there so you can turn the terminal block around so that its inlets face into the board and so that you can run the 30V wires underneath and through the hole to the terminal block.
 
Did I already mention this??

Those do look nice, and so compact for an all-in-one ps/amp.
 
Just biding my time till they are tested and the production run happens.

I think it'll make a fine amp for my HE-5LE's...
