My HW100 is giving me some fits with the alignment for the first time 
in the 39 years I have used it. Usually all goes just as smooth as 
baby's rear. First thing I noticed is that I cannot dip the plate on 
80M, close but not a dip.I decided to just start over.

The het osc setting is first of course. I am curious why the Heathkit 
specs state that it is supposed to be set between -0.5VDC and -2.0VDC. 
I can easily set mine between 0 and -7.4V. Why such a wide range? What 
if it is set for more than -2V?

The actual problem is low power output on all bands and after a full 
alignment and neutralizing the finals with a scope, I went back to 
square one as mentioned above. Any ideas come to mind other than 
swapping the finals? Guess maybe I should compare cathode and plate 
current but that is a pain to do.
