I've been fiddling with the DIYLC app. Fun! My introduction to understanding amps was researching mods for my Blues Jr and studying the Billm (rest in peace bud) website and I remember really wanting a layout for these amps. I'm a visual learner and PCB's are hard to learn from above. I later found our friend @robrob's website and went to town. There I learned how to read schematics and a more in depth understanding. Still learning. Anyways here's my practice in reading a schematic. This is a Blues Junior Rev A with a Rob 5F6a style bias circuit and with no reverb channel. I've also got the schematic copied below. Help me find any mistakes?
