One of them I used a Beseler level adjustment to bring the negative stand into alignment with the base on which the easel sits. The image was still terrible out of focus in one corner while three others were pretty good. One of the other enlargers is still way out of focus on three edges after the negative stand alignment. How else can I troubleshoot this problem? Are the lenses the next likely culprit? They are all secure on their lensboard, and the bellows seem nice and tight. Not sure what else I should look for..

Thanks for any responses
Your description of "Omega pro-lab 4x5 enlargers" makes me think that you are identifying the enlargers by the head that is on them.

What you need is the model number of the enlarger chassis (D2, D5, DII, D6 or ??), and then the instruction manual for that model.

The instruction manual will have instructions on aligning the enlarger.

Harry Taylor is a good suggestion - here is a link to his website: http://www.classic-enlargers.com/. Most likely you will be able to obtain both a manual and advice from him.

Another good source is KHB Photographix (referred to by Harry as "the Canadians"). Their website is here: http://www.khbphotografix.com/. They too are a great resource for both a manual and advice.

Both sources may be able to recommend someone to do the alignment for you.
