Amp DIY – How to Make a Transformers Vacuum Tube Amp!

For those of you Transformers fans who like to tinker with amps, you should really take a look at this great article on how to make a vacuum tube amp.   Very inspiring, I wouldn’t mind having one of these sitting in my living room.

Schematics are available for those up for the challenge.

This past summer I saw Transformers: Revenge of the Fallen and I was inspired to build an enclosure for a vacuum tube amplifier that incorporated the Decepticon logo. The tube amplifier replaces a solid-state amplifier which was driven by a tube preamplifier. For the tube amplifier circuit I used a cutoff pentode (6SJ7 or 6SD7) driving a beam power pentode (6L6 or 5881) in a single-ended circuit (class-A operation). The amplifier schematic is very similar to the one I used for my very first tube amplifier.
