For preamp you need ECC83/12AX7 tubes.
For poweramp EL34 (or 6CA7 or KT77).

The only one I can see that would be of any use would be the 5U4, I think for some fenders and Mesa Booger amps. There are many tubes that you can’t see, so there might be something else of use.

Nope. However, if u ship me the box I will take care to dispose the content properly....

No, but that doesn't mean those tubes don't have some value. The 5U4s are useful in some Fenders and other amps that have tube rectifiers.

Only way to find out is to check each type and see what it sells for on ebay and other sites.
