I finaly got everything together and did it. This amp's first moments in life were playing the first three min of the Eagles Desperado album before the voltage regulator shut down for thermal reasons. Itt took a while to troubleshoot the dang thing, one channel didn't work and had to be almost compleatly resoldered before it finaly decided to coperate. Sounded like crud at first too, but that had something to do with both the transformer being right next to it and the leads for the input and output being around two feet long.
Now it sounds wonderful. I can hear the tape pops from the master tape the cd was made from. The sound doesn't worry me, what does is that for all the talk of the Szekeres MOSFETs getting very hot, mine get warm, and that's about it. I have left it on with music playing/not playing with no load/load, and the only thing that got hot even after three hours is the voltage regulator (which now has a larger heatsink and does not get very hot). It is getting plenty of current and does not distort, should I just be happy and kind of accept it?
On to another note, I am going to use this amp as a preamp for my turntable too (insted of the hissy preamp of my reciever), and am adding a voltage gain stage and crossover to make listening more plesurable. How much gain would be a good for the turntable?
