I was thinking about putting my box of valves (a hundred or so) down in the cellar. The boy'll be four soon and the attic's turning from storage into playroom.
The relative humidity in the cellar is about 80% - it had been raining hard all day when measured but the small cellar windows were closed (as usual). Temperature is about 17/18 degrees, summer and winter.
Does anyone know what valve pins are usually made of? They're mostly 6922/ECC88 and 6SN7 with some Russian 6C45P, GE 211 and Chinese 845.
I'm assuming that the only bits vulnerable to humidity are those outside the glass tube...
