The Li’l Dawg 1 watt amp

I had a good friend & Li’l Dawg owner ask me recently if I’d ever thought about building a 1 watt amp, and honestly I never had but the idea made me think. So I worked up a good layout for the circuit board & chassis and gave it a go. This is the basic FireFly style circuit but I added both a hi & lo gain input to it along with parallel speaker outputs & a line out. The circuit already had a switchable boost function designed into it but with the different inputs you really get a variety of gain structures to play with. The tube compliment is a pair of 12AX7 for the pre-amp, and then a 12AU7 running push-pull for the power tube which the result being a smooth overdrive that goes from clean thru over-the-top crunch and anywhere in between. I’m thinking of adding a simple tone control to the amp but that’s not a problem at all for me as I have the room. While this one was a straight chassis build I think offering it as a LunchBox would be a good idea as well. I’m ready to run with it right now but I’d like to get some feedback (pun intended) on the amp first to make sure I’m on the right track with it. So here’s some pics of the prototype build for now.
