Shelf life of EMT TSD 15 rubber suspension


Hi,

According to info that I found on forums EMT use natural rubber in the suspension and the suspension ages and needs to be replaced every 3 years or so. Does anybody use EMT T TSD 15 that was stored for 10+ years?

If the cartridge does not bottom out when set at the appropriate VTF the rubber damping is fine!

And if it gets hard with age?

I have a number of NOS or near NOS cartridges from when I was a dealer.

A couple after 30 years sound fantastic - as in better than current new $2k cartridges. However most have some attrition, and even though they might track fine, I can hear that the sound has deteriorated.

You records are worth more than the cartridge - I would err on the side of caution and get the EMT serviced.

In high humidity Israel - suspension of TSD lives 1 year maximum... Have lot of bad experience with them.
