AC30_chassis_title

I always loved the sound of a guitar through a Vox AC30 amplifier. The guitarists of my favourite bands play such amplifiers. (Brian May of Queen and The Edge of U2)

Although there are affordable Reissues of the AC30, my interest in DIY led me to try to build one myself.

I am no electrical engeneer, but I am able to wield a soldering iron and have elementary knowledge of electrics. I only built one amp before the AC30, a Madamp A15, a kit with a very detailed set of instructions.

When I saw an AC30 clone by Martin Winterfeld at the Tube-Town Site, I found that it was less complex than the Madamp. So I decided to build my own clone based on his plans and the Hoffmann layout.

However, the amp presented here is the third rebuild of the amp, using a different and optimized layout, which is based on the current AC30HW (2010)
