Left RCA out on DAC not working


Hi guys,

As per title, the Left out RCA socket on my DAC is not working properly.

It will work, but only with RCA plugs with non-metallic shrouds, such as AECO plugs. I only discovered the issue when I went to try other interconnects. I started off with my Lavri Grand ICs which have AECO plugs, but all my ICs with metallic shrouds around the pin don't work at all.

The DAC is relatively new; I contacted the distributor, and he thinks it's a badly soldered ground on the inside of the chassis. He's ordered me a new unit, but has been admitted to hospital for major heart surgery, so I may have a bit of a wait 

Anyway, is he correct in his assumption of a bad ground solder inside on the Left RCA out?

Thanks in advance

My  guess is the RCA jacks on the DAC are pcb mounted and the left jack's hot pin is not soldered (not the ground). The AECO plug is longer than the other RCA plugs and pushes the hot pin back onto the pad, making electrical contact. Board mounted jacks require a large diameter pad to accommodate the hot pin and it is relatively easy to not apply enough heat to get the solder to weld.
