Second important aspect is that if you deal with an amplifiers then you need to understand when clipping comes from. If might come from many locations. The PS in driver stage, the coupling (in case transformers use), or the output stage PS, or the OPT and so on… The Milq was designed in a way that the any power restrictions are coming from output transformers, the way how SET should be designed and the DSET topology would take care of that limitation. So, the primary focus of your in the given topology should be the only the Channel A output stage. If looks like you beef up enough inductance in you OPT of the Channel A, which is good, not you need to make sure that you can pump power to the output tube. Here is there is another limitation. The 6C33C is indirectly heated tube and they type of tube as the enter to the operation what grid voltage approaches to bias voltage (class A2 or the mode of grid currents) then this type of tubes do not do so well and they distort rather hard. The direct heated tubes if you feed them with enough current they can push through a little bit but the indirect heated cannot. You it should be very important to you that in your case your Channel A as the input voltage goes up the Channel stags in Class A1 and the input voltage in the grid of 6C33C does not rise to the rise voltage. In fact, knowing how the Milq is designed this would be the ONLY measurement that I would care as it ejectively demonstrate the efficiency of you LF speakers projected to the acoustic size of you listening room. I had at my site a post where I described the measurements I took and posted my measurements in my room. Here it is:
