[Boatanchors] Globe King 500A tuning

[james.liles at comcast.net]

Good afternoon Charles:

Where can I find a schematic for the 500?  Always had an interest in that 
unit.

Kindest regards Jim K9AXN

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.
