I ordered the 10w amplifier with with the wire terminals but I received the one with the power socket. Can I solder the power wires to the underside of the board? If so, which pins are the + & -? My guess is that it’s 2 of the three pins (2 directly under socket and 1 to the side). Or am I better off just sending it back to get the one I actually need?
Thanks, Jon.
