Thanks ml8, do you know how much it could swing before problems, either due to clipping or grid current?

I would be interesting to know how much plate voltage (and power) 6E5P would have with no bias. If ml8 would promise to try the Milq’s biasing then I will promise to try the no-bias operation :-)…

Surely I would not have in the no-bias operation a power necessary for LF channels but for the HF channels might do it…. if it sound in the same way as the LF channels. I wonder how difference is in sonic signature of 6E5P when Milq’s biasing is being use vs. the use of no-biasing? It is very much possible that they will have different sounds, which would make the stages unintegrateable in context of DSET application… The Milq’s biased 6E5P sounds VERY different then a regularly fixed-biased or cathode biased 6E5P. Ml8 suggests that a drastic change on sound character happens with 6E5P with no bias as well…. It would be interring to try it and to see in which direction the tube goes…. BTW, ml8 did you try driving more current thought anode and getting more power while you were in 0-bias mode?
