This is a mock-up of my next amplifier build. It's a pair of monoblock tube amps.
The base will be made of Oak or some other nice hardwood.. I haven't decided yet. The top plate and the cage around the transformers in the back will be solid copper and brass. The feet are 3/4" threaded brass rod and bolts.
There will be matching speakers to go with them, but I haven't finished the design for those yet.
I've just about finished gathering the materials, and should start building on this project soon! You can follow along if you like on my blog: www.blog.coppersteam.com
