Sorry, i forgot an advantage of connecting several caps between chassis and ground in an unbalanced system: you can do things in order that the "isolated bulkhead RCA jacks" is no more an aperture for RF spraying into the enclosure. An isolated spacer short-circuited with 4.7nf smd caps will give a rather RF tight aperture. It's good news, since many high-end audio equipements, even with 2 centimeters thick enclosure, often behave like RF resonance boxes with slot apertures, pinholes anywhere, "square" layout, wires along the walls, and many other things forbidden for any equipement having to survive in a high RF environment.
Enough for now. I broke the treble level pot of my crossover yesterday night (I tighted its nut too strong after calibrating the system)and I have to change it. It is my fault, this way I learnt never use plastic axle pot anymore (although this pot is a pro cermet one from Bourns)
