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.

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?
johnadlertech OP Details Discussions Posts This discussion Message User 16 posts 04-28-2006 at 05:39pm Copy Comment URL Report Comment Edit Delete 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.

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.
