A Confession

[vts1134]

I don't think any one of us is 100% on the side of either of the two extreme examples I gave. I am certainly not suggesting that anyone should be looked down upon because they choose not to give things away at will. As I said in my last post "anyone is free to keep or share anything they see fit." There are things in my collection that I'm not offering up for grabs! What I am saying is that the more people we have in this hobby the better for all of us. I don't think I would be a tv collector if it weren't for the generosity of this community. When we let porthole fly's, Moto yokes, and spare 15GP22s go to others we keep people collecting and that infects others. Just this week I let go of another rare picture tube to another young collector because he needed it for a family set. This was no only my only spare, but it left me with a broken CRT in my set. Someday a 7EP4 will come around again and maybe then I'll have one to replace mine. In the meantime another collector will have the joy of watching a set that means a lot to him, and that means a lot to me to help him.

Sorry to go so off-topic. Moderators edit if you see fit.

So why not make an adapter socket, and substitute a common 7JP4?

In general, a 7JP4 won't sub all that well for a 7EP4, the difference in HV is too great. The 7EP4 needs about 2 or 3 kV, a 7JP4 is around 6 kV I think. A 5BP4 is a better sub, being electrically identical, despite the smaller screen, and actually cheaper than a 7JP4. A 7GP4 would probably work though...

I'm a stickler for originality. I've seen 2 7EP4's for sale in 5 years so another one is due to come up in 3 years or so.
