"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'd again suggest trying my first idea of switching the right and left cartridge connections to see if the noise switches to the other channel. This will allow you to definitively know whether the problem is with the cartridge or something further down the chain. (I apologize in advance if you've already tried this, but I didn't see you mention it in your subsequent posts.)
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.
