I have a Peavey TMAX 210 combo that I could have sworn was expandable to 300 watts with a cab. I just looked on there and it says 500 watts at 2 ohms. I feel dumb but I don't know what I have now! I was so excited when I bought it that I forgot to get the manual and the store is 150 miles away. I had printed off a manual but now I can't find it and it is a discontinued product now. I posted on Peavey's sight but thought someone here might know. I'm gonna go out on a limb and say if it says 500W then that's what it is right? Duh.
