Ok I have a question on a different subject. I know everything has value to someone, but I have at least 500 minimum. Old tubes for radios and televisions. Any ideas.

Some are really hard to come by. Don't go listing them before you research them some.

Usually they're pretty multi-purpose som they can often be found in all sorts of stuff. Which is good for you, they're not niched.
