I don´t believe that the anode voltage drops to zero volts at 625mA anode
current.
4KV voltage swing in your calculation is probably too high.

Just to clarify, I used 1.6 for "K", which in Ian's spreadsheet is in 
the middle of the range for AB:

Single 8877
4KV
625mA
60% efficiency
"K" factor of 1.6
  = 4000 ohms plate load impedance.
