LTP question

[m6tt]

So here is an idea I had, note the "unbypassed" anode resistor and the similarities to a cathodyne circuit, but spread across the anode. Not having tried it, maybe someone could provide insight? I don't have LTspice, so I can't just netlist it. The signal should couple across the anode similarly to the cathode in a traditional LTP, right ? Wasn't too sure what to do with the second grid, not sure where to tie it exactly. Anyway, it was a strange idea I had and I figured those who've been around tubes longer than I have might have an idea. I was thinking it would save one triode from the cathodyne+cathode followers used in the williamson. Thanks!

Wrong. The plate will not work as an input. (And please, nobody bring up that ridiculous inverted tube circuit.)

I started to think that, and if the anode signal is coupled down to the grid it'll have to be a paraphrase of sorts. Ok, just one of those hmm questions. I figured it wasn't that easy since I'd never seen it, but you never know.

There was a thread about this a week or two ago. It's dissected there mercilessly.
