Static from tubes

After watching and listening to some reviews I decided to purchase a Schiit Audio Freya plus preamp. I replaced the Tung-Sol tubes with General Electric GTBs and at least in my system, the separation of instruments was better. This was in March, 2019. I was quite happy at first. Twice, here was some static right after the tubes were changed, then it disappeared. At this point I am again getting static when I use the tubes. I looked inside and the inserts look pretty cheap (plastic).  Is static common with tubes, or is this unit just have this one part of it that is cheap? I am trying to decide if there is a tweak or repair for this, or if I should just sell it cheap and move on. Any ideas?

Unfortunately for me, if the volume is low I can still hear the static even during play. Thanks for your response. I try to keep a pillowcase over the unit and remove it during play but I was not doing this early on.

Its about 16 feet from my router, but not necessarily from my neighbors. I may have to move where I am placing my preamp if this is the case. I'll talk to my neighbor. Thanks.

@ Newbee both tubes had static that I noticed only after changing the tubes for the third time. I tried a combination, and I used both sets. 

@Ghosthous. changing the tubes is what seemed to cause the static. It started, then stopped after a bit. Then again after another change, and finally the third time the static has lasted longer. I think I will take your and goeffkait's advice and do some cleaning. Then I'll take it from there.
