Boogie MKII-B Colesium 180watts. 15" Electro Voice.
This model is the loudest guitar amp I ever played through.

I figured the choice between a powered up and operational amplifier that is not glamorous or a cool amp that is presently an inoperable project demanded function over form.
I do need to move the Eventide into a more convenient to use place.
Here are some dusty tube public address amps:

Funny, I'm watching an old public service nuclear film (The Day Called X) that starts with a horn like the one you've got in you avatar.

Looks a little rich for my blood.
Here's an old single ended 6BQ5 amp that could drive a set of cans, assuming the impedances were low enough.

Poor old Amperex. I need to freshen this one up, no gutshot today.
