How To: Schematics and Layout for a Hot Rod Marshall

It's been awhile since I've done any "How To" blogs, so I thought I'd do one where I provide a schematic and layout for a prototype of a two channel, foot switchable hot rod Marshall style amp. When I first set out to build my ultimate amp, I built this as a turret board prototype I called the PlexRod. It is a great sounding amp, and there are some clips available of it if you Google search a bit. Many of the ideas in this amp turned into the Cherry Bomb, although the switching and some other things are different.

How To: Punching a Blank Chassis with a Custom Control Layout

When you want to design a prototype for a custom amp, it is almost impossible to find a pre-punched chassis that can be easily adapted to match your control layout. To get around this, you?ll need to drill and punch your control layout on a blank chassis. You can obtain a blank chassis in a wide variety of sizes from a number of online amplifier parts merchants like Watts Tube audio and Tube Amp Doctor. When I was doing my first prototype amp, I decided to get an aluminum blank chassis in the same size and shape as a traditional Marshall 100 watt Super Lead.
