Chassis Ground = Circuit Ground --> Problems?

I'm working on a DIY pre-amp project (for home theater use). The RCA jacks I'm using will be grounded to the chassis due to their mounting design. I'm not planning to ground the chassis to mains ground; however, the chassis will be grounded to both the circuit ground and the ground from the RCA jacks.

I'm assuming that this will NOT result in a problem; but it can't hurt to ask...

Thanks,
Robert
 
Another approach is to attach the chassis to earth ground
through a nice 35 amp rectifier bridge. The two AC pins
connect together on one side, and the + and - pins connect
together on the other. This isolates the chassis and circuit
ground from the AC earth up to about .6 volts, enough for
prevention of ground loops and protection from shock.
 
Does this offer better protection than the regular thermistor?

Also, is this scheme better for circuit ground as well?


regards,
