I have a bunch of old tubes and I'm trying to get a tester currently, but I don't know how to use it and haven't been able to find a good resource on the net.

Any info would be great, Thanks.

Look around on eBay. There are lots and lots of tube testers sold there, and many have the charts with them. With the charts, you'll set some switches and dials as indicated and read the results on a built-in meter. Better testers will test more variety of tubes, and will test more things inside each tube.

There's a few books on tube testing available, and they tell you things like how to get the most out of your tester. I can't recall where to get those books, but I suspect that if you look around on eBay, you'll run across an auction or two that has a link to books like these.

Happy hunting!

He has been very helpful to bunches of folks and he may also offer a deal on testing, but he will surely give his opinion of what you can do.
