So I've had this project in mind for years but now I've gotten up the nerve and expertise to possibly pull it off. I'm gonna meld three of my favorite hobbies... Electronics, Ham Radio and guitar playing into one project! The "Dean-O-Amp" or some other name (I'm up for suggestions by the way). I've been watching a channel on YouTube by a guy named "Uncle Doug" who just finished posting a multi-part series on scratch building a vintage amp. His was based on a Supro, mine will be based on the Fender Vibro-Champ. Fantastic instructor Uncle Doug is plus some great tips and resources on how to do it. Back in 1966 I built this speaker cabinet as a Jr. High School wood shop project and it has been with me all these years serving mostly as just a speaker box for my Ham radio rig. That's my station call sign at the top. With a lot of help from Adobe Illustrator, I had our local metal shop bend me a chassis to fit inside the enclosure that will of course hold the electronics of the Vibro-Champ clone. The circuit is what's called a single-ended output employing (1) 6V6 vacuum tube. I'll explain the vibrato (actually a tremolo) circuit later. There will be a total of 4 tubes, the other three are (2) 12AX7's for pre-amp and tremolo plus (1) 5Y3 rectifier tube. The speaker I propose to use is a vintage 10" 1954 Zenith that is still in perfect condition. I may change it out for a vintage Jensen if it doesn't sound quite right but I'm fond of this speaker because it came out of my very first "Hi-Fi" record player in the early 60's. And here are a couple pix's of the newly finished chassis (sans all the holes) This is how it should sit in the 12 1/4" cabinet... Here is a rear-view drawing: And a top view of the proposed control panel: As you can see, I'm just getting started so stay tuned for my progress reports... Here is the B-Model schematic I will probably use.
