I had an issue blowing fuses with my new amp combo build and posted in the electric guitars and amps section, photos and asked for help. After over 700 views just a couple responded with no answer.
The problem is so obvious now that I finally found it, and to be honest I heard it before I saw it.
So for fun can you find it? BTW you do not have to know anything about the circuit or the components, as a hint.
