I have a Mesa Boogie 400+ and LOVE IT, it has all the power that I will ever need and more, I run mine at 4 ohms and it's a monster. I've had it over ten years and have only retubed it once. I bet it will sound great with the Acme boxes,As far as tubes go, it will cost about $250.00 to retube but if you buy a new one, Mesa/Boogie gave me a half off my first tube order,(don't know if they still do that) but it's the best amp I've ever owned!!!!!
