Make sure you have speaker wires hooked up.
Make sure no signal is going in. Like, no music if pre amp is on.

Amps will not hold bias.
I have a pair of Cary Audio 300B monos that will not hold bias, it is not the tubes as I have several to choose from and the amp's have the issue regardless of the tubes installed. I am sure that you guys probably know what the problem is so I thought I would ask before sending them to Cary.
