Tube CCS

>>connect the interstage capacitor to the lower tube plate instead of the upper tube cathode, and hear the difference for yourself.<<

"This makes it a different circuit of course ... tube CCS"

AC currents through the two sections in the schematic linked by Paul are nearly identical. The upper tube is in no way acting as a CCS, regardless of takeoff point. I am highly suspicious of any claim to a sonic difference relative to the cited circuit considering that only 333 ohms separates the two points being discussed. That resistance is virtually a dead short in comparison to the AC resistance of the circuitry in which it is operating.
