This project was a followup for the guitar I finished in October for my 16 year old son (http://www.bt3central.com/showthread...hlight=guitar). It's a ~ 3 watt class A tube amp made on a 1939 Stromberg-Carlson radio chassis, which was made right here in Rochester, NY. The chassis is stuffed inside an old American Bosch radio....built roughly between 1928 and 1941. I salvaged the power transformer, rectifier tube, and 6V6G output tube from the Strom-Carl. Other parts were obtained from Ebay, spare parts, and a local electronics surplus place...the pre-amp tube is a 12AX7 that I plucked from my Mom's old intercom. It's got an on/off switch w/light, standby switch, master volume, gain control, bass, mid, and treble. It's currently mated to a 12" EV speaker cabinet we roughed out several weeks ago, which is something we'll finish into a presentable package this winter. The guitar, amp, and speaker cab were all custom built by us.
The schematic is a modified version of the P1 Extreme from the AX84 project amp website...fairly similar to the old Fender Champ or Les Paul Junior. We're tossing around the idea of calling it the "Fender Bender", "Night Light", or "Glow Worm". I still plan to cover up some of the scratches and add a handle.
It sounds awesome and is surprisingly loud. Never build anything like this before....a very cool project, and best of all "Mr. Santana" seems happy with it.
Total cost for the amp was maybe $50, the guitar ~ $150, and the speaker was < $20. I should probably add a safety warning/disclaimer....the voltage in these amps are high and can be fatal if you're not careful. If you ever build one and need to probe, be cautious and keep one hand behind your back to avoid the charge from jolting your heart....keep in mind that the filter caps can store a voltage for a very long time....I got zapped twice so far!
Edit: added a handle for good measure...
