The manual must be even more rare than the unit. You are lucky to get a copy, wonder how many were made? I think there were 2 versions, with different lamp drivers.
I also had a couple of 4720’s, used them for several years.

Jeff,
Thanks. Corby got in touch offline and kindly offered to send me
a copy of the manual, now on it's way to me. Will scan and upload
to the usual sites on receipt. Looks like it has all the info
needed to restore it, so long as there is no serious corrosion
inside the modules.
Great winter project, if it cxn be lifted onto the bench :-)...
