Hi Keith - Very good job on your '39!! I'm actually sitting on the fence about replacing some resistors.... noticed a toasty resistor coming off the grid of one of the power tubes so I measured it and was about 15% higher than specified. Those old carbon comps really drift, don't they? By the way, how did you deal with the oddball values when replacing?
I've read the mica caps don't usually need replacing, but I've got one installed in the pushbutton mechanism that's reading 460pf and should be 370pf. I'm thinking of replacing that one just in case.
Just need to replace wires coming from the volume pot and get the power tranny/bakelite block re-installed for a quick test. Will get some pics up soon with my results.
