I have a repaired PDF for you. All I need is your email.
(I had the same problem earlier this week, same question, except mine was a 45M. I found a PDF repair util. It will only show you a sample of the repaired file. However, the entire repaired file is in your temp dir, so I copied it out. Give it a try or give me your email and I will send to you.)
does anyone have the manual for this - I've tried clicking on links from previous posts but none of them work. I just recently acquired this enlarger and would love to have the manual.
