Generally no, especially re-tip. Difficult to do a re-tip that does not damage the cantilever and mount. Also, it is not very cost effective given a shorten life of the cartridge.
Is it worth repairing or re-tipping?
I have two cartridges that gave me excellent service. One is a Blue Point P-Mount I used with an adapter I scored in a turntable trade and one a JVC MC-1 low output MC cart I found in a box of old audio gear I was given. My carelessness caused me to break off the cantilever on the Blue Point and the JVC went sliding across my platter mat when I was adjusting Anti-Skate and VTA and hadn't lowered the stylus guard. I think the stylus tip was damaged and I want to know, if it can be repaired or re-tipped or is it toast. Secondly I want to know if a new cantilever can be installed on the blue point or if it is toast too. Hard and expensive lessons we all have to learn but if there's a fix and it makes sense I want to hear from those of you in the know.
