I think I found the cause of the watt/SWR meter not working is.? Somebody in the past soldered a white wire from the ground terminal of R2001 directly to ground bypassing C2001 which is supposed to be the path to ground.? Also R2001 does not vary from 32K ohms throughout it's range.? R2002 does vary from 0 to 30K ohms as it should.? R2001 is the forward? wattmeter adjustment and R2002 is the reflected wattmeter adjustment.? I wonder if this wasn't some kind of crude mod to disable the watt/SWR meter which would disable ALC allowing the rig to transmit to it's full capabilty way past the normal 100 to 130 watts?? Also I should mention that the live (opposite from the ground side) wire from R2001 was soldered directly to the terminal instead of to the board.? So somebody did something weird in the past.

I attached a couple of pics of the area.? Looks like I'll need to find a 30K pot to replace the bad one along with C2001.? Has anyone ever seen anything like this?
