Assuming the unit has been kept in a reasonably normal environment temperature and humidity and pollutants wise, the only part that can simply deteriorate from age alone is the elatomeric (synthetic rubber) suspension. Unfortunately elastomers weren't as durable 20 years ago as they are now, so it's sort of a crap shoot whether a given unit will be OK. It might work for awhile only to collapse, or it might not collapse but have become so hardened from age that it doesn't have the compliance (springiness) necessary for proper tracking/tracing of the grooves. If it doesn't give satisfactory performance, it can be rebuilt. The question is would it be worth it . . . . . .
NOS Ortofon VMS 30 MkII
I just bought a NOS/NIB Ortofon VMS 30 MkII (haven't received it yet). I'm wondering how these old Ortofon moving iron designs hold up against age (it's 20 years old!). I've read both positive and negative comments about NOS cartridges. It seems that some brands hold up better than others. Has anybody had NOS experiences with this model (or others from the VMS line)? Are the potential problems limited to the stylus part or is it likely that the rest of the cartridge will be affected too?
