Transmitter problem

[rayfri]

hey folks... a technical question.  I think I know the answer, but
wanted
some comments from the rest of the gang.
I have a transmitter with an output problem.  It uses a pair of 6146's
in the
final.  The drive is fine.. the plate voltage is fine.  BUT..the plate
tuning
has little effect when adjusted and the loading control has very little
control
other than by turning it from one end to the other of its range, I can
go from
no power output to power output that isnt the maximum... seems about
maybe a third or two thirds at the most..
I'm suspecting one of two things... either I have to climb up on the
roof and
check the antenna, or else one or both of the finals have started going
south or have gone south...
What's the concensus here?   Or is there another possibility I'm
missing...
