What would you look for to tell if it's gassy? Glowing fog or other light show in the neck? Sorry to be so dense, but I haven't tried any of these experiments -- or had a gassy CRT, for that matter.

Seller updated one of the auctions. Looks like someone was able to visit the seller and test the CRT's One of them is good with great emission! The other has gone to air. If the buyer of the So cal set wins the good CRT we might have another living CT-100 soon!

I wrote the seller tonight to ask their reason for pulling the gassy tube off eBay. Everything has value ... even a dud gone to air.

Then, for about a month each time, I would 'curb shop" with my van and put my finds n the trucks. IMAGINE--what I could find around 1970, in the NY area--a LOT of CTC-5,7, 9 and so on rca tv sets, maybe a few CT-100's and 21ct55's, etc, along with TONS of nice Hi-fi gear. I would load the semis to the gunwales and "bring it all home".

Then,I would take two other semis to 1948 or so..same area...THIS time--prewar sets and nice radios of ALL types. Once again, about a month and back home.

Hopefully he just wants to relist it to give people a chance to rebid knowing the true status.

I was able to chat with the seller today. My understanding from our conversation was that once the ebayer p**u did a bid retraction the bid price fell back to the opening bid of $9.99. The seller said he didn't want to give away the tube - so he canceled the auction. The seller then asked me to make an offer. I suggested he relist with a higher minimum bid. Hopefully, something he's comfortable with. I'll give it another day, but so far he's not gotten back to me about my offer.

Well, he probably wants to wait and see what the good tube sells for. Perfectly understandable; but to those of us who collect and restore old TV sets there's a big value difference between a good 15GP22 and one that's gone to air. I suppose time will tell what that different may be if the seller ever decides to relist the dud.

Ok now that I am the winning bidder I will tell some more of the story.


Pete Deksnis is the person who went over and tested the tube, and he told me that it is VERY good.

So it looks like I will be getting one oif my two CT100's up and running with a new crt berfore very long.

Pete is going to go over and pick the tube up for me. I am not sure when I will have it in my possession. Maybe not till the next ETF convention.

Wow... an NOS 15G... that's gotta give you goosebumps!

Is your CT100 ready for the tube... plug-and-play? Or will you need to do some chassis work first?

The chassis is rebuilt and opperational. I have a 15GP22 under vacuum, but one of the guns has a dead filiment. The chassis was tested with that tube.


My under vacuum, two color tube will be rebuilt on the next trip that John Folsom and I are going to make to Hawkeye. We will be rebuilding 2 under vacuum duds on our next trip. One is mine and one is John's. We are planning the trip for sometime in December if all goes according to plans.

But before I even think of puting my first CT100 together, I need to do some refinishing work on the cabinet. It will probably be well into the first quarter or even the second quarter of next year before I find the time to do the work on my set. I am so involved with the 15GP22 project and our future attempts to seal and rebuild the leaker tubes that there is not much time do do my own sets right now. After we put the 15GP22 rebuild project to bed, I will have more time for personal projects.

Bob

Congratulations with the acquisition Bob! It's a double bonus with the money going to a good cause.

You got that right Tom. I don't think a leaker will ever be worth more than about $300, even if John Folsom and I are able to develope a workable method to seal the leakers.

The bottom line is; rebuilding a 15GP22 ( one that is still under vacuum ) is going to cost more than what I just paid for this NOS tube.

And, if we are successful, rebuilding a leaker will be even more expensive than rebuilding a tube still under vacuum, due to the extra work that will most likely be involved.

Bottom line is.... 15GP22 tubes that are under vacuum and fully functional, will be getting more and more expensive as time goes by because the cost to rebuild these tubes will greater than the today's current market price of a known good tube.

For an animal such as this, you can't expect it to be anything less than expensive. If you're hard core, you'll do what you can to get these things... put up your house, children, wife, land... whatever you can to obtain one of these.

As Bob points out, they will get more and more expensive as time passes. So, if times get hard and you're stuck between a rock and a TV set, you can always get your investment back and more. Of course, you don't want to have to go that route, but, you're certainly not going to lose... at least... not in our lifetime.
