Tube is in the 3rd amp position - (There are only 3 12ax7s in the MX110 - the phono section for two of them and also this position) so to be honest the only other position to put that tube would be in one of the cathode follower positions (now have grey plates in there) of the MC240.
I have had this tube in the MX110 for the better part of a year with no issues - have checked each tube in the audio path in the 110 and it's this one that is the noisy one - tests really well on my Stark 9-66 (just calibrated) and it's kinda confusing about this...
I have put in another black plate in this position and it's fine.
Just really puzzling about it and another BP went howling about a year ago - that was during burn-in.
This isn't.
