It may not be a simple answer such as you have suggested - a loose wire. The eyes play tricks on you (quite normal) but looking at a test strip and a full sized print the eye adjusts for the greys (I presume it is B&W) and your test strip looks correct but as you described the full size print is slightly different.
I have noticed this too with colour as well as B&W, but when placing the dried test strip over a similar area as the test was made on the full sized print there is a difference. With colour there is the added difference of colour balance to make it more difficult. However think of the eye as a camera TTL meter that only takes an average reading. that will almost certainly distort the impression it gives what is the correct exposure all depending on the background - too light and it will make the test appear darker and to dark it will be the other way.. Now think of the finished full sized print being viewed by the same type of 'meter' and you get an all over more accurate impression if it is right or not. With colour I noticed this years ago and keep a well exposed, correctly colour balanced print in the dark room on which I place the test strip where I can judge both the exposure and balance at the same time. I have not tried it with B&W but there is no reason why it will not work. All you need is a good quality print with a full range of tones (or colours) and see what you get. With colour, I occasionally have some difficulty with cyan casts, and I know my colour vision is 100% - it had to be for my job. This way it allows me to notice cyan straight away. |

In addition, a good enlarging lens with very positive click-stops and 'no play' in the aperture ring adjustment, is a godsend and worth every penny! Many enlarger lenses are worthless in that regard.
