Could be the tubes burning in. It might resolve itself after a while.

It's either a normal tube noise that may or may not go away with long term use, or its a solder joint that needs to be reheated and reflowed.

Had this exact issue and it was driving me up the wall, to the point I would leave it for a week and come back to it!

It's a bad solder joint, I had to reflow and/or redo most of mine 4 times (even though they all looked good), then burn it in on a low volume overnight for it to disappear.
