OK but why didn't you put the resistor in circuit diagram too? Where is connected and how much is it.
So I need to wire the + and - to a speaker directly or a jack? I'm confuse.
Man but it is not much simple to solder ground and positive to speaker?
Yes is the best way, but you didn't help with nothing, anyone can locate the problem if the circuit board do not receive power. Please do one with all I need to have in mind, for what to look. Ex: my amp 2x 15w 4-8Ohm it is ok, he receive power but the led is flashing or sometimes nothing. What can I do? (the circuit is ok I don't see any short)
