[Hallicrafters] SX-117 BFO Freq. Adjustment

[Waldo Magnuson]

I use my SX-117 in slaved mode with my HT-44.  I have been having 
trouble with frequency stability in transmitting so I am making 
calibration adjustments to my SX-117.  In following the procedure for 
the BFO Frequency Adjustment (Section 6-11) I find that after removing 
the BFO control knob (step a.) and try turning the BFO slug (accessible 
through the center of the control knob) I find that I cannot turn the 
slug independently of the control knob shaft - as if the two are 
"frozen" together.  I am tempted to try a little liquid wrench to try 
to free the two shafts - are there any other suggestions?  Thanks.

Regarding the HT-44, I replaced several tubes and then tried adjusting 
the Bias Adjustment on the output tubes.  I can't get the 100 ma idling 
current for the final tubes.  Any comments about this would also be 
welcome.

Thanks.
