I've been trying to find equations around the type of cathode follower circuit seen in a Bassman/Marshall - regular triode tied directly to the follower. I'm using this as the first gain stage in my 3-channel ODS-style amp. I'd like to get a little more output from this tube - and was wondering if I could change the 100K to 220K - on just the first triode's plate, or on the follower's cathode, or both. Anyone experimented with this kind of thing before? (I know that I *can* change it - I was just hoping that someone else could speak authoritatively before I whip out the soldering iron.
