How are you grounding the turntable to the phono preamp?Ha. Good analogy. I always thought this too until my current situation.![]()
OK - seen that in the video. The wire is pretty long, can you shorten it. You also have a loop of it over the PSU wire to the turntable (which I assume comes from a wallwart) - try to separate those. In fact keep the RCA leads separate from the power also.
Use your multimeter to check the turntable wiring from the cartridge to the phono connectors. (Disconnect the cartridge first), Make sure all wires connect through OK.
What volume is your amp set to?
And I notice you are in a garage - what is the power connection looking like. What other gear is in the garage running (eg AC plant etc).
Oh, and which turntable, which amp, which cartridge?
