Hey guys,

I cross-posted this to TB as well.

I just picked up a MM 412B cabinet. I want to find the right head to pair with this, but I'm not super sure about what it can handle. I did find a MM catalog from 1980 that lists the 412B as 8 ohms and 150W RMS (p.23/30). However, this other MM catalog from 1983 says the 412B is "power rated at 300 watts" (p.7/8).

How can both of these be true? I do see two input jacks on the back of the enclosure. Is it possible the jacks run parallel so you could run a head at 4 ohms and 300W into both jacks? Is that possible? I'm not well educated on this stuff, and I definitely don't want to guess wrong and end up frying an amp.

Thanks for your help here!
