I had actually considered the safelight being the culprit before. I'm using those red safelight bulbs that Adorama sells and the one on my dry side is about 3 feet away but over my enlarger. I had started turning it off before i printed the test for Max Black which is shown in tge OP. I will use this coin to test for certainty in a couple days to find out for sure though.
And the C700 has 2 condensers...
Throw that effing bulb in the trash and buy a real safe light.
Oh, and thats the correct condensor set.
Turn off the safe light 100%. 3 feet is way too close in any case.
I am sure there is a thread here on properly testing the safe light. Do not fall for the coin test as it is worthless almost.
Haze in the lens will kill contrast and muddy tones. It does not kill sharpness until it gets pretty bad. Shine a pen or keychain light in both sides .
