Why not a newer TNT 350hd??
Right now I run a Texas Star 350, years ago I had a Magna Force 350 (now called TnT 350). If my choice was buy a Texas Star from Crapper or a TnT 350 from X-Force the TnT wins HANDS DOWN. Plus the TnT is a better built amp.
I know the class, how are they applying and regulating the bias.
