Basic Black, full 17" wide and fairly hefty. I haven't been inside but theres a big bolt head on the bottom which says toroid power trans to me.![](http://pic6.audiogon.com/i/c/f/1211758577.jpg)
Classe doesn't have any info on their site and no one at that other site can agree whether it's a true balanced circuit but at least the XLRs are there.

Class-A is the pronunciation, I guess, but class AB is the circuit. I let it cook all night and it didn't even get warm. Just what's needed.
