Re: Cathode resistor bypass cap...what is it there for?
Jim,  
The cap bypasses all frequencies equally above a certain point(the -3db lower frequncy or f1) depending upon cap value and resistor value. Frequecies below the f1 or -3db point are rolled off gradually. There is some good info on this subject on Randall Aiken's website.
