RE: Tube loading chokes?

By "normal range" I mean typical of the plate chokes I have measured or seen measurements of.

Windings are interesting. The L/R ratio is a function of the core and gap, but any winding of the same copper mass will have the same L/R. So if you have 225 henries at 1850 ohms, you could use thicker wire on the same core and get 22.5 henries at 185 ohms. (That's a 3.5 pound choke, in the Hammond catalog.)

If you do layer winding, the self-capacitance is mostly between adjacent layers, and they are in series. More layers, less capacitance. Of course there is winding to core capacitance too, and it may dominate since it's in parallel. But many turns is not necessarily a capacitance problem.
