Well.. it's finished. Found all the problems. The biggest one was apparently my DC supply. Though the range switch was in the 150mA position, it was actually showing the 30mA range. Switch was dirty. Radio is actually drawing about 7.2mA. Also changed out the grid bias resistor, which had drifted from 2.2 to over 6Mohm. This seems to have cleared up a lot of the muddiness.

Had to restring the dial cord. A shame, too, since it had apparently been done in the not too distant past with modern dial cord. But the sheathing had come apart where it went around the tuning shaft, and would not go past a certain point.

Everything works like a champ now. Always amazed at how well these little farm sets pull in the stations. In fact, if I hook it to my random wire (approx. 100'), it's too much for it. I think I can probably blame that on my friendly neighborhood 1.5MW flamethrower across the bay.
