I'm looking for somebody to test some tubes

I don't have a tester or even know how to operate one (but would be willing to learn). After striking out at a few local shops I've looked for a used tester but decided against that since I would not know if the unit functions properly.
So, would there be anyone interested in testing some tubes for me? Probably have 16 or so and am looking to try identify and match pairs as close as possible.

I have a calibrated tester, you pay shipping to and from I'm willing.

I get it and somewhat agree with you doing so and pitdogg2 is willing to do it for you which is pretty cool. BUT my question to you is, what tubes do you have?? Where did you get them from? Have you tried Local Music amp repair shops? They all have tube testers as most guitar amps are tube amps. We have several around the PA Philadelphia and NJ areas.
And finally what does it cost to ship both ways vs buying new matched tubes for whatever you're changing tubes in?Dan

Pennies on the dollar? Jeez, have you seen the price of tubes as of late?
Reliably sourced NOS tubes are a gold mine nowadays.

Unfortunately there are no shops in this area that I know of that can test for me...and have have tried several that I thought could help. One Mom&Pop TV shop said I should have called sooner as they just gave away 2 testers....dang!
The tubes are mostly 12AX7 and 6DJ8 types. pitdogg2...PM forthcoming.Yep, my name really is Bob.

With Ivan, you will have someone very knowledgeable about the tester and its results as well as the construction and characteristics of the tubes he’s testing. On top of that, no worries about his handling of any valuable tubes or potential return shipping/packaging issues.

Finally found a shop not too far from us that will do the testing, BIG thanks to Ivan for the offer though.
Other than fleabay, where would I find boxes for 12AX7 size tubes?Yep, my name really is Bob.

No I haven't and is why I asked. It's been a few years since I purchased tubes. I got 4 Sovtech 6L6 tubes all matched for $74.99. I have no idea what they cost now but I'll have to start looking as one of my Guitar amps is ready for some fresh tubes.
I don't know what NOS tubes are.Dan

NOS = New Old Stock.I don't know what NOS tubes are.
What you are buying Dan is NOT considered NOS as they are still in production.

Not laughing at you but LOL.
That's why I said what I said. Tube prices have gone through the damned roof.
