[R-390] Toasted R216 (2nd mixer plate resistor)

Tim,

Past live stories are that the tube went shorted and smoked the
plate resistor, Since then some has changed the tube.
Did not pull the RF deck for inspection and left you with toast.

Not such a strange thing to happen.
Tubes die and kill plate resistors on a regular basis.
This is why PM was done ever six months. To get the tubes
before the tubes got the resistors.
