Well, it really has nothing to do with it as a CCS gain stage can use either fixed or cathode bias. The bottom tube is pretty much a conventional grounded cathode amplifier (and can be biased as such); the only difference being that it has tube on top acting as a high impedance load in lieu of a simple resistor. This provides a much better load line (almost horizontal), leading to far less distortion.Naz
