The good news is I now have broadcast playing! The bad news is I'm still not sure where the short is but have narrowed it down. In poking around I found that the two ends of the volume control pot showed a dead short when I checked resistance. I looked for a mistake in my wiring but could not locate it. In checking around the R2 resistor in the tone switch assembly I pulled the 9A Alto switch into the "out" position and that solved the short across the volume pot. Just for the heck of it I powered up and found that I now had broadcast playing, a little hum but not bad. At least I'm closer. More checking....
