Thanks for pointing me to the field coil. I did have a pin problem with the 47 complicating things with intermittent function, and now I'm convinced that the field coil is open. The radio is dead until I short the field coil, then it comes alive. Of course I then have over a hundred volts on the screen grids. I have a 1930 Dayfan speaker that I am able to fire up including the field coil, while I can't get any magnification out of the Philco speaker. I do get a small amount of sound out of the Philco without the field coil. I see speakers for sale often emphasize "working field coil". Is it common for these to open?

Looks like an expensive fix but I'm into this so deep I have to do something. Either a loner radio or a salvaged speaker? Does anyone repair these?
