Are those tube in usable condition ?

[New in town]

Hello,

i purchased a pair of sylvania tubes 6ca7 for my guitar amplifier but there are some visual issues with them so i didn't dare to try them.

here is the first issue one tube has remnants of glass floating inside.

the second issue is that the wires which support elements of the tube (i think it is the mica support) are burn and one seem to have exploded because it is almost cut in half :

so what would you say about those ? are they in normal condition ?

Thank you,

Could you give me some explainations on the burnt, cut in half, tip of the wires in the picture ?

is this a sign of overheat or bad usage ?

You have me on that one. My system is all tubes but there are members here who are very tube and tech savvy. I’m betting they will see the thread and reply. You certainly posted the thread in the correct subforum
