5e3 tweed to PS-100 wiring setup

I’m trying to attenuate my Femder 57 custom deluxe but use the speaker that is in the combo. It has a male end on it. Any ideas on how to wire this up or is my only option to get an extension cabinet and put the combo speaker in that?

Hello, Here is a diagram from the PS-100 user manual that shows how to do this. You’ll just need to obtain a 1/4" female TS to 1/4" female TS adaptor and a short speaker cable. Cheers! Gil
