Right, by tuning out the C. Fun story: I read the J. Williams book, and was thinking about fast photodiodes. I thought, "Hmm I wonder if anyone used a T-coil with a photodiode front end." A search and bingo! I discovered Phil Hobbs.
It was notes from some talk at a school. (Colorado?) I couldn't find it again... but scroll way down here.. page 75.

One photodiode circuit (for people who don't believe in noise) dumps the diode current into a resistor and then amplifies that voltage. Add a small inductor in series with the resistor to peak things up.
The thing about t-coils is that they are hard to make. It has been done with wire bond loops!

That's better - in that schematic there are small trimmer caps between the anodes rather than shorts, presumably to trim the waveform response.
I've used an Agilent 7-stage one to drive an optical modulator with ~30GHz bandwidth. I think it provided about +/- 4v differential output.

Right - the whole idea of the distributed amplifier is to make the tubes' plate to ground and grid to ground capacitances parts of discrete-component transmission lines.
The trimmers are to compensate for differences in tube units. There are more trimmers in the discrete delay lines to the deflection plates.
I don't know the answers to all your questions unfortunately. :( I don't touch the drink anymore tho it's not good for u. soldering and sex are my only "vices" these days you might not think these things would be a "crossover genre" but you might be surprised the kinda topics one can bring up on a first date that at the very least makes a lady think "Well, he's at least a bit, ah, different than the other bros"
Heh. Helps that I'm still young. My consumption has been up this month, working a consult job with a major corporation. Needless to say, I do not miss the corporate life. ;-)
Cheers!

Why would anyone want a circuit like that? You don't even have real feedback. Is it some kind of tube distortion emulator?
