After turning my kaiju on just now, before starting music, I noticed a high pitch hum coming from the amp. When I put pressure on the bell end it completely stops the hum. It's loud enough that I now notice it during quiet passages in the music. Any ideas what could be wrong?

Power transformers will vibrate.  Make sure your screws are tightened fully.

Thanks for the suggestion. After warming up/playing for about an hour the hum was much less noticeable. I did tighten the screws once it cooled back down and while there is still a very faint hum it's nowhere near as loud as it was at first.
