Glad you guys are back!
Some of you may have seen a preview post about this work in progress...here's some pics of the final look. It's a companion for the guitar we built in October. (http://sawmillcreek.org/showthread.php?t=43739&highlight=finally)
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. I salvaged the power transformer, rectifier tube, and 6V6G output tube from the S-C. 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 that 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 right here.
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. The chassis is stuffed inside an old American Bosch radio box....built roughly between 1928 and 1941.
It sounds awesome and is surprisingly loud. Never built anything like this before....thought it was a pretty cool abnd "educational" project, and best of all "Mr. Santana" seems happy with it.
Here's the before and after pics:
