Based on the online project the AX84 guitar amplifier, this project is a homemade 15 watt guitar amplifier. It uses 12AX7 tubes in the preamplifier stages and EL84 vacuum tubes in the final output stage. The chassis of the amplifier is constructed from a modified Digital Microwave Radio Corporation modem chassis. Using hand tools and lots of creativity the chassis began to take shape. I mounted the power transformer as well as machined the rear connection plate.
The rear plate is inteded to provide a sturdy mount for the power connector, fuse, and the interconnects for the preamplifier and final output stage. I want the freedom of being able to use just the 12ax7 preamplifier stage or just the final output stage. The machining of the rear plate involved using a drill press, tap and die, and metal files. The finished rear plate looks symmetrical and well built which makes me very happy to have done. After some rubbing alcohol to remove the sharpie and some buffing, the finished piece will be very nice and include additional space for more connections if needed.
