1936 Philco 645
#22

Is everyone tired of questions about shadow meters? Well, I'm going to try one, anyway. My meter works pretty well; but with power on, the vane's no-signal position (the detent position?) is not centered. It remains somewhat left of center, and it deflect only to the left. With power off, the vane goes back to dead center. I'd like to look into the section with the coil, but I'm not sure how to do it without risking at least esthetic damage to the device.

I see six tabs in front, the "a's & b's," two side-slots at the rear, the "c's," and one tab, "d," at the back. It looks like there's a slot at the rear to pry and lift the upper case and possibly rotate forward, but it doesn't budge with gentle force.

So, is the vane supposed to deflect bilaterally? Is there anything I can fix to correct the centering? And finally, how the heck do you crack this thing open?
