Help with ground loop hum

Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

I have a ground loop hum that I have isolated to an active crossover used for my tapped horn subs. The hum is just loud enough to be annoying. I can attentuate by connecting a clip lead from the chassis ground of the active crossover to the chassis ground of the monoblock amps. I'm looking for assistance for what else I could do that would not require this separate wire. All of my powered equipment uses 3 prong plugs and are plugged into the same circuit. The ground loop appears to be traveling back through the ICs from the active crossover to the TVC to the amps. I know the noise is not filament hum.

A simple schematic of my system is attached.

TIA,
Jim
