Having just accepted the fact that my tube has expired, I've decided to spend the 2 grand for replacement tube, X,Y axis PM kits and new optics. Is there anything I should know before I get out the screwdriver and band-aids? A cursory inspection looks like this should be something I can handle as long as I don't open the back and find I need a moss covered three handled family credenza to get the tube out. Anyone done this repair on a similar machine?
Thanx,
Jim
