Hi Audioquest,

Unlikely it is the power supply unless perhaps you are running 1 supply per channel. Do you have volume controls?.... rotate them briskly with the source off for 10-20x... If none of this applies to you: 1.) remove and insert existing tubes to clean contacts & listen then 2.) switch tubes left to right until you find the culprit. Also check your connections to source and pre. via interconnects

I have an IO sig with 2 supplies an volume controls.... It is remarkably quiet. It will take an hour or so but you will find the tube if that is the case.

Having things off for a while should not affect things. Only where things are left out without tubes in sockets and dust collects does this happen. Bad spot of luck or coincidence.

Good Luck,

AJ
