[Amps] Henry 4K Shunt Resistor

[Bob Maser]

My manual for the 4K Ultra calls for the shunt resistor (R16) to be 470 
ohms, 1 watt.  Somebody crossed out the 470 and wrote in 1K, 1 watt.  Can 
someone tell me what the plate shunt resistor should be?  I am getting low 
readings on the meter and I suspect that the shunt resistor is too low which 
is taking amps away from the meter( Poor wording perhaps).

Thanks,  Bob  W6TR
