A question regarding amps and ohms here... i've played guitar for years but always relied on combo amps up to now and never had to worry about such things! I apologise in advance if this question has been asked and answered here before!
My rig consists of a Marshall JMP1 pre-amp and a Behringer Virtualizer Pro running through a SoundLab Go97 power amp, and i've just got hold of a Marshall 1936 2 x 12 cab.
The power amp has two speaker outputs and states on the back "Stereo. 90W 4 ohms. 60W 8 ohms", this is not switchable though. The cab has two inputs and states "Mono input 150W RMS 8 ohms" and "Stereo 75W/CH 16 ohms".
What i would like to know is... am i in any danger of damaging any part of the rig or the cab if i run the whole thing in stereo.
Many thanks in advance.
I'll respond and to be honest I'm not sure I understand all this as well as the others. I know Wes Inman knows this stuff in his sleep so maybe he'll throw some of his knowledge out here.
As I see it, your cabinet is rated to accept a hotter signal than what your amp is putting out. So to me, there shouldn't be a power issue at all.
Now if your amp was pumping out more power than the cabinet(s) could handle, you could blow the cabinet.
But I think in this case you are safe.

Is your amp stereo? If not then there is no point in running your cab in stereo. Your amp (if it would even work) would put out a lot less power if you ran it at 16ohm.
Is there a bridge for the outputs?
