Problem with amp section on a rci 2990..Losing dead key works like a modulator..Keys about 1/2 a watt swings to 175 watts..Problem is NOT in the variable or the main board..Anyone seen this before?
 

Does it have an NPC mod? That's what it sounds like.
Usually a diode and small resistor over by the regulator.
Not that i am aware of but that regulator is getting Hot when keyed the one on the amp board..No mods and it was working up until a week or so ago and it started doing this

    So I have a cobra 138xlr and the meter dose not work... It dose not key up and signal dose not work.... It is not stuck it the meter moves freely. now wires are resoldered on both ends...So now that do I look at. Could it be a diode or a transistor?
