RE: parallel cathode bias resistors: "ghosting" effect


Hi. The Rk resistors are made to be identical, so as not to ghost.

Multiple bypass film caps are purposely selected to be non-identical, and serve a different function.

Each value of film Rk bypass cap will play a different part of the audio spectrum, and a linear-sounding "overall combination" of multiple bypass film cap values gets to be selected and determined by ear.

A single Rk film cap will "tune" to the single cap's value. Film Rk caps are not linear when playing music, despite rudimentary sine wave bench testing.
