bent stylus questions


the stylus cantilever on my Grado Statement Reference is bent to the side about 15 degrees, seemingly right where it is joined to a slightly larger tubular thing (which is oriented straight). I have no idea how this happened, but it is bent in the direction toward the spindle. Once I started aligning with the cantilever, using a Mint, and ignoring the cartridge body (which you have to ignore with the wooden Grados anyway, due to their funny shape), things improved greatly, and may even be about right. Is the sideways stylus nevertheless a concern? Is it out of the question to try to bend it straight with tweezers and magnification, or would I just inevitably destroy it? As far as I know, Grados are apparently never rebuilt, only good for tradein.

Lloydc,

If you're serious enough to purchase a Mint protractor, why would you consider using a badly damaged cartridge? The possibility this cartridge can still play as designed is now zero.

Aligning the outer end of a bent cantilever makes the best of this bad situation, but no alignment can nullify the problems Pryso described in his 5th paragraph. The imbalance of vectors at the inner end of the cantilever means that the movement of coils relative to magnets can no longer be as Grado intended. That guarantees uneven channel balance, uneven dynamic responses and perhaps uneven frequency responses.

Further, any bent material is necessarily less rigid than the same material unbent. A less rigid cantilever weakens dynamics and bass. It may also exhibit resonance issues at some frequencies, depending on exactly how the molecular bonds were damaged at the bend.

I'm afraid it's now a junk cartridge. Use it knowing that or have it repaired/replaced.

Sorry,
Doug

P.S. to all, Lloydc has a bent cantilever, not a bent stylus (unless his stylus is a pre-LP era type made from something other than a gemstone). Diamonds wear, diamonds break, diamonds don't bend.
