I am in the same situation where I have large amounts of 12AU7, 6SN7, BH6, AU6, and such that are used in wide apps. Most are loose. Most are untested. I find testing lots of non valuable tubes tiresome and only do so when I need one for something. Maybe will test 3- half dozen and pick the best for something I need and mark the rest unless they are bad or marginal. I defy any of you to tell me any possible reason to save something like, oh, 4 volt miniature tubes used in TV tuners unless you collect old TVs.

Because someone will buy a box of loose tubes like that at auction for $25. :-D. I'm not making this up.

I used a 4AU6 in one of the transmitters I built, heater in series with the 9KC6 RF output. I've found 6GK5, 6HA5(or 4HA5, 4GK5) etc make great audio preamps.

Save then because nobody makes them anymore. I don’t understand throwing any of this stuff in the trash, someone will come and get it and hoard it or use it. Even with the hoarders, at least it’s not in a landfill somewhere. I’ve got bunches of random tv tubes, which I will never use, but they will be there for someone.

I've offered several small lots of various unboxed, untested tubes here in the classifieds for postage, over the last few years. All have been snapped up, so I presume they went to good, caring homes, lol. I knew I'd never use them.

I finally reached my goal of having 25,000 good tubes.
The problem now is accessing them. Just today, I pulled 6 packing boxes of tubes out of the living room closet. All of them were full of compactron sweep tubes. The octal sweep tubes are still in the garage.
Tubes all over the house, and I started thinning out the herd - pulled about 2,000 tubes out so far. I still need to go through the UX types and the miniature types. They didn't seem so heavy when I put them away last year. Also, I don't think I'll need 153 6J5 tubes.
The plan is to sell them for whatever at the hamfests. They are separated into TV and non-TV types. Dampers and HV rectifiers are tough to get rid of.
I'd consider selling some here, but many of them are not boxed.

No tubes are truly worthless. Just consider the space they take up, which is protecting you from buying even more worthless stuff ;-)

Price is too high with the shipping, change it to $10 shipping included.

6W4 damper tubes were used as bias rectifiers in a lot of 50s and early 60s 1kw broadcast transmitters, particularly Gates, so a few hams who have salvaged those might need a few.
