Fred -
The LOAD settings shown in the manual are only approximate, for a 50 ohm
load. Easiest is to always tune the TUNE and LOAD controls for maximum
output, and finally dip the Plate current with the TUNE. That should
ALWAYS be the last adjustment. If you want to run a little less than
maximum output, then reduce the LOAD control slightly (toward 0) and
again, DIP the Plate current last.

/Just a question./
/ I have been using the load settings that show in the manual for the
T4XB transmitter. It says the load control should be at 3.5 for 75
meters and 4.5 for 40 and most of the other bands. I noticed that when
I reduce the load control the output increases. Any thoughts on this?
Which do most of you use. Should we follow the manual or just look for
max output? We tune the plate for max output which does correspond to
the dip in plate current,so that seems fine./
