Romy, are you saying you are squeezing up to 60W from the 6C33C, and the mid-bass is still clipping?!? There must be a better way than cranking still higher plate dissipation!
If you need more than 60W from the 6C33C for mid-bass now, perhaps it is time to take another look at the output scheme, at least the amplification stages? You might get by with greater efficiency; or you might just need more line gain for more power at the tap. I understand what you are saying about limiting frequency response, but it is still hard to believe the 6C33C sounds its best - including LF - when it is that wide open.
I remember you would not consider parallel output; but maybe this is a case where you could kill two LF birds with one lower-output-impedance stone?
Best regards,
