I don't wish to enter this fracas, but I would point out a piece of
"free-ware" available from KD9JQ's web site that quickly calculates this
parameter as well as a number of others. For those of you who may be
interested in this software (about 110K), it may be seen and or downloaded
at www.imaxx.net/~kd9jq. Some of the experts may sniff at the prospect of
being able to design triode amps, quickly, from a menu of tubes, but you may
want to check it out before rejecting it. It sure has come in handy for me,
a non-engineer who just enjoys building amps.
