Henry,
Have emailed twice and left messages on the voice mail and contacted the customer service dept. who promised to have the tech call me.
Still waiting.....
Jon,
After carefully examining the unit, I believe, in spite of the appearance an adjustment can be made, the lens stage is like the 23C in that shims must be used to adjust the fore/aft axis. It does not have a tilt adjust like the 23 does.
However, if anyone has the enlarger and has encountered the same problem, please feel free to share your experience.
Thanks to all,
Fred
