Hi guys, I've just tested my resistive load box with a Peavey Windsor runing two EL34's and found out the OT is "making noises". It's not actual vibration but sounds like it. Really weird.

Is that OK or am I going to fry something really soon?

That's normal. They do that

Thanks!...that's a relief. Now I can go crank that mofo up.
