Hi to all. I just picked up a nice used Ampeg B2re and I have a question about it's power output. The manual that I got with it tells me that it's 350 watts @ 4 ohms. But on the back of the amp(see pic) it's telling me it's 450 @ 4ohms. So I just wanted to get some input about what the real deal is power outage wise. Thanks in advance for your comments.
