Recommendations for very low watt circuits to build
« on: February 07, 2019, 06:33:28 pm »
Hello all. I've been thinking it might be fun to put together an ultra low wattage amp - maybe 1/2 to 1 watt. I've already built a 5F6A and a 5F1. I would consider building a micro version of one of those designs but would probably prefer something different. I'm looking for something with only two or three tubes that I can build in a small enclosure. The Boot Hill Six Shooter looks interesting. Any other designs out there I can check out? Anybody built something similar that they can recommend?

A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!
