RE: what CCS for a 6sn7 driver tube

Your description indicates that you have built a parallel SE KT120 amplifier, is that correct? If so, the 6SN7GT driver triodes are operating as SE drivers, so a CCS in the cathode will only work if the cathode is bypassed to ground with a capacitor and the CCS "negative" terminal is connected to a negative supply of a few volts. It's a bit more complicated than I expect you realize and won't really improve performance much at all. The better place for the CCS would be as an anode load for the 6SN7GT drivers, where the performance will really improve. The anode load CCS will not have a thermal problem if you choose the heat sink properly.
