I dug this one out last night because I really want to get it working, but I somehow made it worse. Build Doc here: https://drive.google.com/file/d/1t9UkjtPVxwSyIMK1RBP7tvHhX9SKaRui/view
Initially, I got a sound that just sounded like it was completely voltage starved, but at least all the leds were working and there was sound coming through. I reflowed some solder joints - there are admittedly some pretty ugly ones in there - and reconnected the power, input and output. Now I get no sound at all and no led indicators. What's weird is I tried tracing the circuit and hit what seems like a problem right at q1 (BS250 mosfet), I'm reading 8.83 at the Drain and 0.56 at the Source pin. I've reflowed, checked the pinout, used an xacto knife between the joints and legs, but keep getting that reading. Everything after it checked at random reads around .4-.4v.
