I am converting my Randall combo to a head / cab and have reached the point of having the amp removed from the cab and the speaker wires ready to be connected to a jack.
The jack I have looks exactly like this with 3 pins on each side. My question is how do i now connect the 2 speaker wires to this jack?

Thanks for your help
ok, this jack is a bit different but the connections are the same. i'm assuming you want the internal speaker switched off when a plug is inserted, so that's what this diagram does. if you want to REPLACE the speaker with a jack, ignore the "to speaker in amp" wires.

so for my purposes i would just solder the 2 speaker wires i have to the pins marked "From speaker outputs on PCB"?
