A friend asked me to build him a small amp. I've been looking forward to a Micro build, after considering my friend's requirements and some ideas of my own, we arrived at a design with the following: - Micro Bassman PP power amp and phase inverter using 12BH7 for output - solid state rectifier - Tone control - switchable parallel boost stage - bias-wiggle tremolo w/ MOSFET oscillator and blinking LED - Master volume - relay switching with 2-button footswtich Here's the schematic: Faceplate design: Faceplate is front-engraved acrylic. Chassis is a Hammond 15"x7"x3". All the transformers are designated on the schematic, but I chose the larger Hammond 125C output transformer (8W) and a power transformer with 315-0-315 HT secondary for a target B+ of 420VDC. I'll be building this on terminal strips only. I will probably do a quick DIYLC layout before assembly. I expect to do some gain stage balancing, tweak coupling caps, and blow up some MOSFET's before calling this build final. It's the most "original" build I've done so far. Most of it copy-and-paste from other builds of course, but most unique overall and therefore some uncertainties. The tremolo circuit is the biggest wildcard, I believe I can get it to work but ready to roll with the punches! Parts are on their way. I got some new tools I get to use for the first time -- a little nibbler, vintage radio punches, a drill press vise, some new cobalt drill bits, and a riveter. Stoked!
