Hi all

I've got a Marshall JCM 900 Mk3 2100 head into a Marshall JCM 900 1936 cab.

I'm running a speaker lead from the 8ohm output on the amp to the 8ohm mono input on the cab.

Problem is, only the left hand speaker is working.

I've tried connecting 2 cables for stereo, using 16ohm from the amp. Both the speakers work fine then, but I read that I shouldn't do this.

Not sure if the cab wiring is faulty or what, so any help would be greatly appreciated! Thanks in advance!!

Someone might have screwed the wiring on your cabinet. You should be able to plug into the "mono" input and have both speakers working.

Do you have and know how to use an ohmmeter?
