Hey Lew!
I am building a pair of amplifiers that will have a tube SLCF, which Allen Wright has worked out for me. It is quite similar to the Paul Speltz circuit.
Allen also advised me to rise the heater on the ccs (v3) and the tube that is connected to the cathode of the cathode-follower above ground (negative) to stay within the spesificasion from the tube manual. This also give a sonically improvment. (A separat transformer is needed for this)
Right now I am trying to make a ccs with LM 317 for each tube on the DC driver heater supply.
If nothing goes seriously wrong, and my work don`t consume to much of my time, I hope my amps will be finished during january.
