because, as you say, that would reduce the required size of the bypass capacitor. I calculated in my head that to achieve a -3 db point at 2Hz with a 30-ohm cathode resistor (so response would be flat at 20Hz), I'd need ~3000uF bypass caps. I'm sure one can get by well with a higher -3db point, however.
With my amps, that's a lot of new parts to buy and install (3 cathodes times 4 tubes per monoblock), if I were to do it. 24 new resistors and bypass capacitors, in total.
