In Reply to: RE: Question for Banat posted by Banat on February 19, 2014 at 08:07:09:
If we posit that the cathode resistor is used to promote current sharing and that the steady-state DC bias current will remain essentially constant during music reproduction, then we have AC current variation during music reproduction, only. So if the bypass capacitor shunts all audio frequencies, i.e., all AC, around the cathode resistor, does it not also negate the capacity of the cathode resistor to promote current sharing among the output tubes, when we listen to music?
This would be an especially important consideration for me, using 7241 output tubes, because of the need for cathode resistors to help the 3 internal cathodes to share current as equally as possible.
Thanks.
