Thanks for another great guide, vid. I'd replaced a couple of broken lamp sockets in pops, so I knew a little already, but this guide taught me more.
Coincidence: a friend came over 2 nights & ago & I noticed that my Meteor pop didn't light up. A few pics on-line showed that it lights up. (The higher coil-less bumpers do light up at the appropriate times.) I opened up the pop & saw no evidence of there ever being a socket or wiring for a bulb in it.
I had an extra 555 socket with the sheet metal leads from my previous pop work. I installed it carefully per your guide & wired it in parallel w/ the GI 44/47 bulbs.
Voila! Now my pop lights up. It actually bothers me a bit--I'm not used to it yet... :]
Thanks,
