Got the blue LEDs in today and swapped them out. As easy as you said and it looks AWESOME. (I replaced two lamps in each meter, but the package came with five...am I missing one?) Here's the real issue, though: I brought it up on the variac again just to have more control over voltage and also to pay attention to when the loud buzzing starts (the 140 service manual mentions a variac, so I think it's ok...) The buzzing starts at around 90v and gets pretty intense around 110v, and then all of a sudden "click" and the buzzing stops. I do it a few more times and I see that the sound is coming from a clear box in the rear with a spring in it and something that looks a cap with omron DC24v printed on it (what I now know is the power relay). Big problem? I know I need to get this recapped and serviced, but I'm hoping that this power relay issue won't be too difficult/pricey to fix... Thanks in advance for any help!
