I know what you are thinking. Heat retention.

But the glass has a lot of surface area. For a low power amp it would be fine. You could also put a quiet low power fan in the base and put in some holes for forced circulation. The bell jar can go through the dishwasher once in a whole if dust builds up.

Stereopile had one a few years ago that used 4CX250s or some similar blower cooled tubes that was in a cylinder and filled with a clear oil for coolant. It looked like an embalming machine to me, and I never saw a picture of it again. An oil leak would be a domestic disaster because you’d never get it out of the carpet.

See the picture for an idea…..just bigger and with a flat base. Atwater Kent made a radio like this too IIRC.
