As my kids used to say when little, "But WHYYYYY?"
I'm thinking you are talking GG.
More P than plate V*I => Lower Z than plate V/I.
Source I is more than plate I.
Am I right?
What about a grounded cathode triode amp?

| Good question, Jon
|
| For 8877s, 3cx800A7s, 3-400Zs, 3-500Zs and similar high Mu triodes,
