My Route 66 head is vibrating when you turn it on. Even when the head is on standby with just a speaker plugged in, the amp vibrates. It feel similar to putting your hand on the side of a refrigerator. This seems really bizarre to me, as there are no moving parts in it. The amp seems to sound and play fine. I'm running it through an airbrake into a 12" speaker.
I've swapped the KT66s and EF86 and re-biased. Please tell me something isn't horribly wrong with it.

New one to me. Make sure the transformer is snug. I hope it's that easy.
I do remember my uncles old Marantz power amp having a vibration to it when you felt it, but it didn't affect it. Good Luck.

I took the chassis out and checked everything that could've been loose, but nothing was. The vibration is still there but it's not as strong as when it's mounted in the cabinet. It definitely feels like the transformer is the source of the vibration.
EDIT: After doing some searching on TGP, it seems that vibrating transformers are not uncommon. My next question is: could this cause any problems down the road? I plan on playing the dog$h!t out of this thing and I would hate for it to give out mid-gig.
