No right channel in new cartridge

I just got a Sumiko Blackbird & mounted it.  I have no right channel. I haven’t fine tuned the mounting but, That shouldn’t make me lose a whole channel.  Once or twice I’ve heard a hum in the right channel before I put the needle down. When it goes down it stops & goes silent.  The channel isn’t effected in CD, DVD or radio.

i bought it here(all positives on the seller) & it only had 10 hours on it. It didn’t come in the original box but came screwed into a box... seemed pretty secure.  I checked & reconnected all the pins, jacks into the AVR & ground wire.

What should I try next?

You’ll have to get it under a microscope, stereo biological, or maybe 5.0+ reading glasses or whatnot. Super close ups, fine focus with a close up capable (macro) cell phone, maybe.

You are going to have to check the ultra fine wires that are exposed on the body. they are open to having problems from human handling.

While it is possible to check them with a resistance meter, it is strongly advised to not do this.


Checking the wires is only part of the litany of things to check. more information is required, do you use detachable head shell turntable arms, for example.

You imply, but don't say explicitly, that the cartridge functioned in both channels at some point after you purchased and installed it into this very same system.  Is that the case?  Or was it "dead on arrival" in the R channel?

Try reversing the leads from your turntable to your phono section. Does the dead channel follow the reversal? If not, you can be sure the problem is not the cartridge.

Buying a used phono cartridge is always an iffy proposition.

Lewn, it was DOA. No just meant the person who sold it to me said he had 10hrs on it.

Tro, the head shell is part of the arm. it’s a Rega 200.

cleeds, the dead channel follows when I reverse the leads. That would mean it’s the cartridge?
