Well, it looks like it was what I had but until you reminded it I did not recall. The key is that it was not with my amps bur with the amps of my local guy. You see, his amps were sitting for a long time and the sockets wend bad, rusty. In your case you use the amps dally and sine you clean the sockets one and then keep the amp in your home then the sockets shall not go bad.
You still are missing however point what I do not believe. If your socket is failed then socket has no contact or bad contact to one of several tube pins, the way how it was in my example above. However, you do not report that you have no contact but you say that you “keep getting noise from the 12AX7/sockets, and this noise gets resolved when you clean the connectors”. I do not know any NOISE that might derive from bad sockets contact, particularly in the case of ML2. In ML2 the 12AX7 ran both half in parallel, so it is very unlikely you might have any problems with contacts and I personally know no circumstances under which a bas contact would cause any noise for a line-level signal.
