pm Bigkidz. He was a repair person for counterpoint and now builds his own electronics.
contact me  I have someone buying a few old mosfets from me now  so if you are looking for those I may have a few left over

If you want I can replace the mosfets with bi-polar transistor and offer upgrades to the amp that make it world class  see my system for a picture

Happy Listening.
