Glad you got it worked out. Makes sense, since the 39A compensator at the low end has a lot more adjustment range than 40, the high end compensator. The dial calibration lines are more compressed at the high frequency end, so just a slight rotation of the dial makes a bigger correction than at the spread out low end. Really what they did was set the high end dial calibration by shifting the dial and then corrected the low end with the 39A padder compensator.
That resetting of the index in the 38-116 procedure is a bit of a fudge. Never saw a procedure like that before. Guess someone at Philco originally made a mistake in laying out the dial and then production just offset the index alignment to compensate.
I assume that now, neither index lines up when the tuning cap is tuned to the end stops?
How does the color of your repro dial compare with the original? I bought the same repro dial from Radio Daze a few years ago but was disappointed in the color and translucency. It was made of a rather dark phenolic material, a lot different from the amber colored original. I wonder if they are using better material now?
