So, I spent all day rewiring the R200 tone arm on my Rega planar 2. I soldered the wires from the bottom of the tonearm into a DIN female, and made a new cable with a DIN male connection. Was a pain in the ***, but now the signal is constant. Buuuuuut the right channel still has no signal. Tested both lines with the multimeter and they come out perfect.
Tried swapping the rcas on my amp, amp is fine...
Any idea? It had this problem before, as well as general instability from bad wiring. Signal coming and going, etc...

Measure the resistance from hot to cold on each RCA plug from the tt.
Do you get the same readings (roughly 1k ohm typically)?
Is one of them open circuit? Probably the cartridge.

Hey Jeff,
It's a new cartridge. Well, used, but just got it from a reputable audio place.
Switched the connection at the cartridge, still no sound at all on that channel.

Did you test continuity from the cartridge pin to the RCA plug with everything together? Did you cross check continuity from + to - with the cartridge out? Maybe you have a short.
Yeah I checked resistance from RCA plug with cartridge in. Both channels read the same.
Also, checked each line individually with cart out.

Then the cart/arm/tt should be ok. No short, no open.
Play an LP and scope the tt RCA outputs directly.
Do you have signal on both plugs?

Sorry, Im a noob..
What do you mean here?
"Play an LP and scope the tt RCA outputs directly."
I'm using an Arcam A18 integrated amp which has a phono pre-amp. Goldring 2200.
I notice I can hear ground hum or bits of noise while handling either RCA plug. That goes away as soon as they are plugged in.

And you've swapped the RCA's going into your amp, so you know that's not the problem?

Ok, super weird, now it works... I'm guessing there's probably just a bad connection somewhere that kept closing when I'd test the lines and open up when I plugged it in. So, I guess I have to never touch it now and hope for the best....
You could have damaged the wire insulation while assembling and sometimes it shorts with the arm movement.
RCA plugs sometimes do bad contacts. Check.
