Back from the trout trip. Sunburned, and tail between legs - didn’t catch a thing. But my two buddies were able to net three very nice 3-4 pound rainbows. Yeah, that’s BIG! Maybe next time….
Anyway, just got done messing with the QMX+ and I wish I could see something conclusive. Interestingly, the “331” inductor that I thought was broken was L101.
Per your suggestions, I have continuity between the + of C504 to the + of D502, so L501 is not broken.
Since I thought L101 was hosed, I also checked the + of C107 to the + of D106, and the neighbor of L101 (L102) from the + of C106 to the + of D107. Continuity there also.?
I applied power and measured the voltages to ground from the + of C504 and D502 on key down. Both showed about 2.9vac. I also measured it as DC and it jumped all over the place from 1 v to 5 v.
I hesitate to remove C505 to check it but if you think at this point it is worth doing, I can give it a shot. What’s the worst that can happen? :-)
Any other suggestions?

Stan and Jeff - thanks for the hints on how to proceed. Got a trout fishing day coming up on Tuesday so it’ll be Wednesday before I can get back to the rig. Will post back results.
