Just measured the F-connectors. The old one for the MX-500P has a centre pin of 1 mm, the new CV has 1.2 mm.
Open connectors, inner diameter on old is 8.9 mm, on CV-version is 9.2 mm. By closing the connectors you can get both
to abot 8.3 mm inner diameter. The problem is if you want to get the CV-version to 8.3 mm you have to screw the outer
shell so it protrudes 4-5 mm in front of the actual connector.
Whatever I try I can't make the CV-hand-piece run on my MX-500P.
Returning it. Will wait for your findings
