New here....having channel/power supply issues with amp and/or graphic EQ. Hoping to gain some knowledge and suggestions to correct the issues. I regularly loose left channel....if I partially unplug the EQ (Pioneer SQ-550) to a half-way loose-ish insertion I can regain stereo. First guess is bad power cord, but I'm no expert. Looking for other thoughts, recommendations and/or actions to take to correct the issue.
The power cord would affect both channels in the same way.
Old equipment can have many issues, such as: dirty or corroded switches, pots, and connectors; bad cables; bad solder joints.

Check your interlink - cable between EQ and amplifier. Try another cable instead.

Stretched RCA plug I suspect, cheap RCA plugs are always doing this. Nothing to do with power, the circuits powered up or nothing would work at all.
