RCA wires... disconnect one ground inside, if jacks are connnected?

Everyone else says to have earth ground to the chassis, and I am nuts not too. Should I just have system ground (star)?

I could also remove the connection from chassis to star ground.

I see andyr (above) has suggested grounding the chassis but he also say's to isolate the entire circuit from the chassis, including using isolated RCA jacks which don't let the ground ring contact the chassis (hence the comment about having to build his own equipment).

This will work fine also (maybe best) though I would definately recomend a ground plane or faraday cage be used in that case which is grounded to componet ground not chassis ground.

What you don't want is for the mains ground to be connected to the componet ground.

There are others whom I see from time to time who mistakenly think that the two conductor power cord supplied with their componet is a flaw in the design (or cost saving measure) and set about installing a three conductor power cord and grounding the chassis.

As explained above the idea with unbalanced systems is maximum ground isolation.

I disconnected the star to chassis ground and it seems to of reduced some RF, or the levels anyways. The sound is a little better too. Voices are more 3D. That was something I could not figure out why it went away a little bit back.

I guess the 330pf capacitor between pin 7 and 8 is what I have to do to get rid of the RF, or put R1 back in (not happening, hardly possible, and would make it sound dull again, R1 was the series input resistor). The is a known problem to have some RF without it, but the capacitor fix should work.

Thanks everyone for the help to determine exactly what to do.
