Anyone know how to eliminate this.

I bought a used RX and on adding a cartridge tested on anotheg RX there was a loud hum in the output.I traced the RCAs and found one plug was shorted and not in good condition. I replaced the RCAs with a new cable and now I get A noise whenever I play a record or raise the tonearm.

The good news is no more shorted input to my amp.

Any ideas where this relay sits, or do I have to live with it?

 

Thanks
