replaceable does the old Rotron CX-33, used on many FM broadcast stations. The CX-33 is still rebuildable, even though out of production for years.


Goodrich used to sell rebuilt CX-33s but they were $700 each. I modified several by drilling out the housings where a punch could be used to tap out the old bearings. This helped in 24/7 service but I suspect a 33 would outlast most of us in Amateur service.
