Greg custom built these Class A boards for me a few years ago. I had planned to use them to drive an open baffle project but we moved into a town house, that project was abandoned and I put the boards in a closet. I was looking for some bits yesterday and I found the boards/power supplies and thought someone might be able to use them. One power supply is assembled and one is not.

To avoid future problems for you and a buyer, please note that these amps are NOT class A!
I have a pair and they are very good; low noise, low distortion and sound great. But they are biased in normal class B, if with a relatively high Iq.

Okay, but at the time I ordered them I requested that Greg assemble them as Class A output and he assured me that they were.
I don't want to rain on your parade in the least, but heat-sinking for class A (what power output and rail voltages?) is a major problem with just a pair of lateral mosfets on such a small assembly.

I remember there were discussions on his forum about operating his amplifier in class a and a number of experimenters increased the bias and by using larger heat sinks were able to operate in class A. I think whoever buys these modules is likely to be somebody who has enough experience to work out those details. They can also be rebiassed to aB.
