    4x12 wiring question

    Can anyone tell me what the ohm are with this. Its a mf400 and the label says 8 ohm but the mf400 should have g12k 100 and today I opened it to find vintage m30's which are suppose to be in the mf280. They are 16 ohms and I believe they are wire series/parallel and all the diagrams I fine online say that makes it 16 ohms. Guy at GC said that 4 16 ohm in series/parallel makes 8 ohms but I cant find a diagram to confirm this. Ive ran the mode 4 at 8 ohms the whole time ive owned it but just got a tube head and want to make sure I'm running the correct ohms. Top of the cab is on the left of the screen.

    Looks like 16 ohms. I'm not 100% sure since the center post is obstructing some of the wires, but each side of the cab appears to be in parallel, and the two sides are in series with each other.

Which is why many people play electric guitars but very very few of them are actually musicians.

      Agree with distrust. Parallel wired in pairs, then the pairs are in series. 16 ohm final load.

        Thanks that's what I was getting from all my searching as well. Guy from GC is full of $#!+.
