Greg Ball GB150 based Class A amplifier boards and power supplies.

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.

$100 USD plus shipping from V9P 1B5.

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.

Thank you for that clarification Bigun. Chapeau.
