You might also want to see the WLW 500 kW equipment which Fyler (at
General Electric) wrote his paper about. Those RCA UV-862 triodes
were 60 inches long, with 21 inches from the filament connection to
the plate radiator! Lucky to get them to play at 1 MHz without all
sorts of physical resonances due to the inductance and capacitance
there.

Jim Hawkins has other excellent photos of transmitters and sites at
his main pages.
