Now, that`s a good info, thanks! Must find a time to read it more carefully...:-)
About Cw - Cw=68pF is so good that I don`t have any "criticism" - even with "worst case" Rout=14k driver (pentode, cascode), we`ll get f-3 ~ 76kHz, good. Even if this figure is doubled (140pF), "good enough" f-3 of ~52kHz can be achieved with 300B tube...
