might be tube rattle

I just built an amp with a similar problem - swapped in a new 12AX7 and it went away. Sometimes there is a node on the chassis that is prone to vibration only at certain frequencies.

That was the first thing that I tried and unfortunately it didn't work for me.

It sounds like a physical rattle to me. It is a combo, correct? First thing I would do is run the speaker out to a separate speaker and make sure that no vibrations can get back to the electronics. I have a Fuchs combo that did something very similar, although not as prominent. I chased tubes, etc... turned out to be a resonant vibration in the cabinet crossbar vibrating agains the bottom of the chassis. Weatherstripping solved it for me. Good luck and make sure to let us know what you find.

Can be a ground somewhere too. It seems not to be signal because that stays with us when it ffffffffts.

That is definitely cold solder joint noise. When the solder is bad or you find that you didn't even put solder on an eyelet or turret that is how it sounds.
