I'm pretty sure this was in the barn for at least the last quarter century, I'll have to ask the person I got it from. BTW it's the same barn I got the Duo View from, it's not well sealed but the roof doesn't leak and it's in So Cal so not too much humidity, but yes. lots of dirt and Mouse poo, in fact I cleaned out a large nest that was built on top of the TV tuner!
It looks like the cap came off the CRT at one time, it's glued on with Epoxy and has solder on the pins, there's a slight possibility that one of the wires is just not connected but I have to figure out how to remove the cap to see, also it's the original Philco tube and the gun looks high mileage so odds are it's kaput anyway.
I have a junk Hoffman with a good 12" tube I could probably use if all else fails, I definitely want this set to work and be original, so no way would I replace the changer!

I might see if there's a way to hook up a 45 player to it though.
