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.

This is known problem by EMT. Despite all feed back information they

deed nothing to solve the problem. Van de Hul first cartridge was his

version of EMT. He use different damapers for his own cartridges and

is the right address for the new dampers.
