This is a short video on a tube glove. I've used many things but there's nothing that beats a tube glove. It's always best to let tubes cool down before moving them around but there are times when this is not possible.

The tube glove for guitar amps enables you to get a firm grip on a hot tube and gently set it down or move it to a new socket. This one is made by electro-harmonix and is a must have if you are handling tubes.
