Need help determining NOS Tubes value, 95 tubes


I need to sell a large box of NOS tubes from my works storage and I dont know much about tubes. I would like to pull those with value to Audiogon members and list them in the classified section. I have a friend of a friend who has a tube tester. But due to time, number, and fees I only want to test those worth something. The rest will go as a lot or two on Ebay. I was able to find 11 matching types for sale but I know that # alone does not determine value. Can anyone help me sort the gold from the junk? And what is a good $ to ask? I dont want to give them away, I just want a fair price for the good ones. Thanks.

I have some tubes that I cant find settings for on this tester. It is a Eico 625. Of them I would like to test the #83 tubes as they seem to have value. Does any one know what to set the tester for?
Well last night I started testing. The tester used is pretty basic, but it did the job. Some tested excellent, most ok, and a few bad. So it was definately worth the time. The few high dollar ones I might retest on a more comprehensive tester that has been offered to me. Not sure yet if I want to bother testing those worth under $10. The people I met last night gave a lot of info and comments that are helpful to someone that is just learnig about tubes. Its amazing the hugh $ range that they go for.
Thanks to those that sent PM and have expressed interest in certain tubes. Special thanks to Restock for all the links. I fould all but 2 of the tubes on tubeworld.com. It took awhile but now I have a good starting price for all of them (of course his are fully documented). Now I need to do a test on those that are higher dollar (one pair is super rare $, most are not). I have been told the tester avaliable is very basic but at least it will show they work. I believe most are totally NOS. Most in boxes, some bulk stock. It will take a week or so before I list in the classified, but when I do I will give first picks to those that showed early interest. Again thanks, now I have a good idea which tubes are most used in gear today.
Your best bet would be to call Andy at vintage tube services. He's one of the best in the business.

hope this helps
