[Boatanchors] Globe King 500A tuning

After a month of doing fine on 80. 40, and 20 CW, my Globe King won't 
tune properly on 80. On 80, plenty of plate current off-dip, but no 
proper dip at all, with minimum plate current and max output (less than 
100 watts) at minimum plate tuning capacitance. Works great on 40 with 
350 watts out and normal tuning. Somewhat degraded on 20 but functional. 
This is same on antenna and dummy load.

My prior attempt to use it on 15 failed similarly with very low output 
and red 4-400A plate, but now 80 while 40 does fine? Does this make any 
sense? I have used Deoxit on all switch contacts.
