Re: mismatched sections

I think I can answer for Jim, since he e-mailed me privately with a pdf for the 7241. Each tube has 3 heaters, 3 cathodes, ONE grid, and ONE plate, so I don't think one can externally correct for internal imbalance, if one cathode is current-hogging for example. However, I have built my Atma-sphere MA240s such that I can individually bias each of the six output tubes (currently 6C33Cs), so perhaps I can use the 7241 if I can find enough tubes that are reasonably internally balanced. (By separate biasing I can to a degree compensate for differences between tubes.)
