Need help with DIN to RCA phono cable troubleshooting


Somehow, I am currently having an issue with an apparent ground problem with my DIN (female five pin straight connector) to RCA phono cable. The arm is a Dynavector 501 mounted on a custom plinth, supporting a Garrard 401 table.

There is a reduction in overall volume, bass frequencies are MIA, and this is all accompanied by a loud hum. I have tried doing a continuity test from a spare headshell to the ground cable, and RCA terminations. I can't tell where the ground was interrupted, I need guidance in how to test for proper continuity in relation to signal and ground leads. Also, I don't know where the shielding should be connected, so a thorough explanation will be needed.

 Thanks for any help that can be given.
 Regards,
 Dan

Noromance, it's not the cartridge, I've switched carts, same result. I've found additional info at vinylengine.com, and will see where that leads to.

Thanks to all for your help.

While the above discussions make me to feel like a mental midget, I am happy to report the problem turned out to be a bad rectifier tube in the power supply section of my Modwright SWP 9.0 SE phono stage.

The comments posted above will be great reference material should I ever turn to balanced connections in my analog front end.

Thanks for all the input, regards,
Dan
