From Rob Robinette's library, the SLO Nakid Micro, a stripped down SLO 100 preamp into a 12BH7 P/P poweramp, making about 3 watts. This little thing has some serious bottom end for such a low wattage, it'll get your windows rattling and knock things off your walls and shelves with little effort. Its a little brute with more gain than anyone would ever need. PCB designed in EasyEDA, board milled on desktop CNC. Absolutely shoehorned my 9.8" PCB into a Hammond 10x"6"x2" chassis, had to bend it open just to get the board in there. PT recycled from an Ampex reel to reel, Hammond 159P choke, Hammond 125B OT.
