For what it's worth, the zero-signal anode-current or idling current on 
my 204F for a pair of 4CX1000A operating Class AB1 at 20% of rated
anode current has it sitting there drawing 2.5Kw of primary input power
when the plate is on, on a two-tone test at 1.5Kw peak output the input
power is about 3.52Kw, a two-tone test at a full 2.5Kw peak output into
a load the input power is 4.2Kw and for a CW signal at 2.5Kw average
into a load the input power is 5.5Kw. So when I say loafing at 1.5Kw
out I do mean a light load on the unit at legal limit when needed.
