new bulb fixed the MPX light, guess the #47 was messing up the bias. It now comes on like a switch and is nice and bright. Before it would always glow dim and just get a bit brighter (but still not very bright) when the MPX was detected. Not to mention the transistor was getting warm that drives it (warmer than it should be).
Only thing left is the SPDT on off. Not sure how that is going to go. my guess is a burned contact. It closes when the button is pressed, press again and its off, but will come on if the turntable is on.
