"Spitting" Cartridge problem


I've run into an issue I've never seen before and can't figure it out. I have an Ortofon Rondo Red mounted on an early TriPlanar on a Basis Ovation table. Recently the right channel has started making serious distortion on transients - it sounds like harsh static/spitting.

VTF, VTA, alignment are all good. And I haven't changed anything either - it just started happening out of the blue. The cart has maybe a few hundred hours on it. Could it just have gone bad?

It's not the phono pre, or anything else in the chain. I can't see how an interconnect could cause such an issue but it's captive so I can't change it easily.

I did check the clips but maybe not good enough. I will clean those suckers with a good degreaser and make sure they fit very tight (with judicious use of a very fine needle-nose pliers). I am now betting that's it as well.

Wgallupe, I don't think anti-skate can be the issue, since many tables/arms function just fine with no anti-skate - right? Also, that static would not just be associated with transients,I think.
Good idea, Bill. I've used the pliers on many occasions and being very careful, never mushed one closed. I'd bet it would be a bit of a pain to deal with if one did do that.
NOPE...

All leads were on VERY solidly. I removed them and applied some Walker SST carefully to the leads. No change.

I am pretty stumped over this one.

Oh, I also completely disconnected the anti-skate - also no change. And checked the VTF again.
Ok, figured it out! The cart (through my Tom Evans Microgroove +X) is overloading the electronic volume control on my preamp. No problem with another pre.
