Help With C-800g Tube Replacement

Hey guys, I just replaced the tube in my c-800g with one from Sony (with tape shield) and made sure to use thermal grease (Arctic Silver). I fired her up and hear a ringing buzzing sound up to about -33 dbfs when normally my noise floor is 50-60. Couldn't find any instructions on how to do it, I did have a little trouble connecting the tube but ended up getting it in there all the way without jamming it. Do I just need to let it warm up/burn in or something? Thanks.

I'm not sure what thermal grease-Arctic Silver is but we use Radio Shack (Archer) Heatsink Compound (silicone base).
After replacing tube, we'll leave it on for 20 hours & let it "sink" in.

Don't know what your ringing buzzing sound could be ... ?

I got it for mounting a cpu cooler to the cpu of my pc, figured its the same thing. Maybe that's the problem, does it have to be a silicone based grease, I think mine is silver/aluminum? No instructions for doing this, ugh... I'll go grab some silicone based grease and try that.
