Question Storing spare tubes

I have a small (maybe 5"x7") pack of replacement tubes in a protective case that I wanted to store behind the speaker in a combo amp (Reverend Hellhound) so I always have spares. Is storing things behind the speaker detrimental to the sound of the amp?

Not at all. I have built combo amps where the working tubes are close to the speaker and no problems.

Only becomes an issue when the roadie has too much to drink and throws the foot pedal on top of them, breaking them!

Maybe I wasn't clear on what I wanted to do. Rather than forget replacement tubes, I put all of them in a small pack to store in the back part of the "compartment" behind the speaker.

One potential issue could be blocking cooling airflow, as there is a cooling fan back there. Another issue could be (depending where the pack of tubes rests) blocking sound airflow to the speaker.

It's probably not worth doing, but I just wondered if anyone stores stuff behind speakers in their tube amps, or keeps that area open.

Pins tubes dont like humid places, especially pins like 6C33/41.
