I bought a used enlarger maybe 25 years ago and am finally in the process of setting it up. The panel light is out, any tips on changing it? Also, the set screws for the focus and expose dials are loose. The smallest Allen wrench I have is 1.5mm (~0.060") and is too big. Are they .050"? Lastly, is there an online manual for this enlarger? Thanks in advance.
