Happy New Cab Day to me! I've been looking for an alternative to my 1936 2x12" or a couple different 1x12" cabs. There's no doubt everyone loves the solid tone out of a 4x12", but I'm getting to old to lug those beasts around. I found a 1989 Marshall 1965A 4x10" in decent shape with the original Celestion G10L-35 speakers. I measured the DC resistance and it was around 13 Ohms. I thought these were supposed to be wired series/parallel and 8 Ohms. Is this going to be a big issue?
