Crt has printed on the boards 1N5819 as rectifying diodes. Those are 40Vr max Schottky diodes. I would feel more secure with MUR120. He uses 2X12VAC tranformer for a long enough time now without diode failures, but it will not be broadly compatible. People can have higher transformers already in their parts collection, or may want to go for the shunts alone and for much higher Vout needing circuits.
With 2X12VAC 50VA transformers the DCin will be enough and the dissipation on the current source Mosfets secure for powering the DCB1S audio section. The 2X15VAC thing was a spin off when double bridges were to be used by the ''first GB manager''.
Still no problem for those who have the 2X15 models, but as I saw they tend to use some sinks on the CCS Mosfets. Heats up the 7812 too.
So I guess that in the BOM, MUR120 and 24V C.T (2X12) 50VA is an adequately safer, cooler, and quality choice as to be the standard.

Probably the resistors were put in backwards
Seriously, I've killed a mosfet before. I would test those...
I dont see a paypal payment from you in the account. Are you sure you sent money to the right address?

yahoo?
If you did forward the paypal reciept to me, I can check against real name etc. Some people have not included username etc.

I see prices but no address. did it get changed?
