Material of bell on transformer?

[jamesondrums]

Does anyone know what material the metal on the bell is? I'm really hoping it's steel.

Transformer bell ends are usually steel, and, judging from the occasional spot of rust I've seen on my Bottlehead parts, I'd say that's true for BH gear also.

Yup, steel.
