does the noise change or go away at any different volumes, does the level of the noticable noise increase or decrease with the change of the volume? Are the tubes seated very well on the circuit board?

I RECENTLY PURCHASED A PRE 2L COMBINED IT WITH MY ADCOM5802 AMP RIGHT AWAY IT DID'NT SOUND RIGHT SO I ORDERED 4 NEW TUBES PHILLPS 6922. INSTALLED THEM NOW SOMETIMES I GET UNBALANCED SOUND FROM THE SPEAKERS AND A VERY NOTICIBLE NOISE ALSO I NOTICED ANY KIND OF TAPPING ON THE PREAMP GOES RIGHT TO THE SPEAKERS NOT TO MENTION IT SOUNDS HORRIBLE EVEN WITH HIGH QUALITY INTERCONNECTS [TRANSPARENT SUPER XL] PLEASE ADVISE WHAT TO CHECK NEXT
