Started messing with the SX-42, today, and have the Sam's Photofact for the radio. I put power to it with the "poor man's variac" and was delighted to see most of the tubes glowing, all was good. I let the old girl warm up her toes and then put the 120v. to her. All was well and more glow. Yippee! I switched over from "standby" to "receive" and the magic smoke was coming from the carrier meter adjustment pot on the back of the set. Powered down and saw that the Clarostat 500 ohm pot had a hole in the side and was definitely shorted. I place a 1k pot in it's place and powered back up. More smoke. I took the meter out, powered back up and more smoke. There is definitely a lot of current going to the pot leads. I am trying to trace the schematic but it is a convoluted circuit. Is this indicative of a component gone bad? I just hope that this isn't in the bandwidth switch as that is a monster. All help is appreciated.
