Joe -
Perhaps this is too simplistic, but have you removed the switch and gone
straight to the dummy load?
If you increase the RF GAIN does the plate current / output power increase?

Garey...
A little more background and specifics... All was working perfectly
fine until I had the bright idea to employ the use of an "el cheapo"
antenna A/B switch to change from my Drakes to my modern rig. I went
to tune up w/ the antenna switch in-line and this is when I noticed
that my plate current was WAY lower than it normally is. Normally, a
the beginning of the tune up sequence (with the XTR gain at 9 o'clock)
I get a reading of .2 amperes of plate. After the tune up is complete
I usually see the plate at .3 or a little more. Now the most I can
muster is .2 amperes. The RF tune has little or no effect. Max out is
a little over 10 watts. I was getting over 100 watts easily on all
bands before. Could my finals have failed? I am no technician but, it
seems like this would have happened more gradually.
I am getting plate current, just way down from where it was at.
RF tune does peak but, it's way down from where it was. Only about .2
amperes.
I've gotten the same results on all the bands that I've tried, 80, 40,
and 20.
Thanks for the help!
