Howdy. Tim here. I was the one who purchased the one for $305....a buddy of mine is going to fetch it for me for free.
It was more than I wanted to spend, but aren't they all.
I know that these can be a pain, but I just love the looks of these sets. I am sure that I will need help getting it going, and since I plan on watching it a bit, I am sure I will be looking for extra picture tubes as well as flybacks.
