Sharing experiences is what DIY is all about, so I thought I'd share my troubles with my El-Sol.
Population went well, with one exception. I mistakenly soldered the board power lead to the battery lug of the DC adapter. This was discovered and corrected during the visual prior to live testing.
I typically use a 400Hz sine wave + oscilloscope + audio probe to initially test the circuit before even looking at a guitar. I guess I just can't stand for that first chord to bomb, ya know?
This is the good part...so I check the cold circuit and all seems as it should. I throw 9v at it, and the scope shows a waveform, but not clipped at all. The audio probe has sound, but nothing like 2-386s should sound....it was more like El-Beano. Power down.
Checked the schematic...oops, no schematic. No problem, it's fairly self-explanatory, even for me. My gut said bad chip, and that turned out to be correct, using a Ruby-type breadboard. Unfortunately, it had burned the trace between pin 6 and the 5817. Thus, the title. I may try to jump the scorched path at some point just for a giggle.
I have another board, so I won't let it turn today into an El-Bummer !
