How long have you had the CRT running ? I let them run for a few hours or even overnight when I first get a set. It seems after siting around for decades they take a little while to wake up.

Really. I had no idea. I just let it run for maybe 5 minutes or so. So I guess I need to give it a try, nothing to lose at this point. I'll hook it back up to the tester and leave it on emissions test and check it in the morning.

Well, it looks like my luck has run out on this tube . I left it connected to the tester in the emissions test mode for a good 12 hours and I am still not getting any meter movement on the emissions. I tried the rejuv again and no change. Looks like my excursion into tv restoration has come to an abrupt end . With my limited budget my options are few. I would like to thank the members that have helped me out thus far - your advice has been priceless .

I hope a 12LP4 finds it's way to you somehow. You never know what may turned up at a garage or estate sale.

If you do find one or decide to work on another set, I'd avoid using the rejuv. function. It can easily blow off all the cathode coating and leave you with 0 emissions.

I'll keep my eyes open for another tube down the road. I really did not want to use the rejuv. function but I felt I had nothing to lose at that point. I'll keep reading the posts from this forum also. Really a bunch of nice folks and brimming with good advice. For now , I will pack this project up and look for something else to come my way.

Sorry to hear your CRT is weak, I know it's a big let down. Did you by chance try testing with a slightly higher filament voltage- say 7-8 volts? If the emission comes up at all, that would give you some indication if the tester is working correctly.

Something will show up eventually, but it can take a lot of waiting. Keep your eye on the local Craigslist, even for what looks like a junker set. You never know when a good CRT is lurking in a ugly old cabinet.

In the mean time try to find another restorer in your area and verify the condition of your CRT tester. Best of luck.

Kevin

I haven't tried a higher filament voltage. I may try it later on. Wouldn't you know it. There's a 12LP4A up for bid right now on ebay. Of course my finances are shot , so I am going to have to pass for now. I wouldn't even know what a fair price would be for something like that. I would actually prefer to deal with a fellow VK'er .
