Just completed the second Mark III and now both are up and running. Very sweet sound as compared to my "Optimos Lateral Mosfet Solid State Power Amp" I have been running them for about 9 hours now. I had to rebias them two times as the tubes are breaking in. I Love these Poseidon drivers!!!! See pics,

I notice that the power tranny's get kind of hot, the output tranny's stay kind of cool. The Weber copper cap rects. are working out nicely allthough they get hot also. I am temporarilly driving these with a Carver C-4000 Preamp and an ADC SS-412X EQ. I am in the process of building a tube based preamp to drive these fine Mark III's. What an exciting project. I may delve into low power audio next. I was thinking of the AD-1 directly heated triodes for the output tubes. I will use this setup in my office. Yellow_Light_Colorz_PDT_11
