Anyone else getting a high-pitched whine out of their amp? It doesn't make this sound when there isn't music playing...but on almost every recording there is an almost unbearable dog-whistle kind of sound, around 12-14 kHz...
Also finding it to be pretty bass-light, lacks heft.

Might be the microphonic tubes, the vibrations from your speakers make the tubes squeal, try lightly knock each tube with your finger to find microphonic ones.

Sounds like microphonics. I would upgrade the tubes. Keep it a bit further away from your speakers can help too. If nothing works, you can also get dampeners.
