Before we learned the hard way (it wasn't in the 3CX1000A
data sheet in 1970) about the need for "glitch" resistors to
limit fault current, tube arcs usually DID **EXPLODE** the
#28 wire in the B&W 800 rf anode chokes we were using.
I distinctly remember a couple hundred half-turns of wire
scattered throughout the rf section - figured it must be the
magnetic field created that blew the thing into nice symmetrical
pieces of basically UNBURNED wire.
