Marshall Valvstate 8008 power amp

Re: Marshall Valvstate 8008 power amp

The 8008 is rated at 80 watts per side at 4 ohms. I routinely run this amp into a 212 stereo cabinet with Emminence speakers rated at 8 ohms each. If I want to, I can run this same amp into two cabinets rated at 4 ohms (two 8 ohm speakers wired in parallel). I COULD (if I wanted to) run this amp into two cabinets rated at 16 ohms, but my volume would be reduced. Four ohms IS the bottom line. This amp (and almost any other amp I can think of) running at 2 ohms WILL fry (there's no debate here).

What do you know.... I was right all along.

Yes, you were!

Re: Marshall Valvstate 8008 power amp

it's even more important that you pay attention to the resistance, because it's a solid state amp.

Actually it's the opposite. Tube amps are more susceptible to failure if impedances are mismatched, particularly the output transformer. Solid State amps are much more forgiving and many don't even list an impedance rating. With tube amps you should at least have a higher rated cab impedance than the amp's output impedance.
