help with suspension collapse

Post by Vinai1964 » 21 Jul 2019 02:03

I've got Technics 100CMK3 from a Japanese Auction site for about $355. The description was clear that it was untested and in storage for a while. So, the seller could be honest.

After arrival, I mounted it on my Sony PS-X60 (PUA-7 tonearm). I found that the suspension must have collapsed. Is there anything that I can do to salvage this? Playing at 1.2g and 1.0g doesn't make difference. The belly is less than 1.0mm clearing from the surface. I am playing it at 1.0g and it seems okay. But I feel that it could be better at 1.2g.

One more question, how much change in sound quality is caused by a collapsed suspension?

I don't think there's anything worthwhile you can do. It cannot perform optimally this way. You can attempt to bend it down, with the high likelyhood of breaking it. Even if that works, it will never be right.

Last resort measures:
Remove the stylus from the cart and take some photos of the stylus and front on views of the cart, where the stylus fits.
Maybe there is a Technics stylus assembly to be found somewhere that will fit or can be adapted to fit?

It's rather a sad and expensive story............

Thank you. Once in a while, a replacement stylus would be listed for an astronomical price. Doesn’t worth it.

Details on this cart:

Possibly some of the EPC205/6/7 styli from Jico and LP Gear are candidates here?

Hi Collux,

Thank you for your suggestion. I got a couple of Technics 205C MK II. It looks different, and I don't even dare try. The better path would be to send it for retipping to Shibata tip on boron cantilever.

But that will be low priority because I just burned a lot of money on NOS Grace G565F Tonearm and “A” grade used Grace F14 + 3 styli.
