Phono cable not caps to le with preamp?

@ghdprentice  I have done this yes. I also tried various different cables and plugged into different outlets. I also moved the power supply as far away as the umbilical allows and moved the unit itself away from everything else.

my cables are shielded and have never had this issue.

if I unplug the input RCA’s it’s dead silent. If I plug them in it’s an overdriven buzzing sound that is affected by the volume on the line stage. 

I just had a thought. Since the phono and power supply are in wood boxes instead of metal would they’ve more susceptible to interference?

@ghdprentice ​​@lewm

got home and swapped cords again. I get sound from both outputs. Playing with the ground alters the tone of the buzz a little bit that’s it.

old phono preamp back in and quiet as a tomb.

seems like sloppiness here but I know nothing about soldering (see my system pics for the guts of the new phono)

EDIT: funny enough I just realized the ground from the TT was never connected to the Andover. And yet it’s still dead black quiet. 

@lewm it’s a buzz. Like overdriven guitar sort of. I put the old phono back in (Andover SpinStage) and it’s dead silent again.

ill play with it tonight and see what I can glean from it. I’m in touch with the importer as well.

edit: forgot to mention the phono stage is plugged into an isolation transformer.
