I recently got a 44 magnum and experienced this too and also a shed load of hum. Really disappointed as this issue is spoiling an otherwise good piece of gear. Not sure what to do about it, wondering if maybe it’s down to a low quality power supply that came with it. …
Put a wire fr chassi of 44 to ground in your power outlet. Hum problem fixed,
