Power grounding question

[falcott]

When connecting the 2 power grounds in a 2-channel GC to the chassis, is it okay to ground both to chassis (through resistor/cap in parallel)? -- or should there be a connection between the 2 power grounds, and only 1 of those connected to chassis?

Ideally, I would say that both PGs should be connected together, then from the centre of that link the chassis connection should be taken. But if I do that with my amp, the centre point of that link is very close to where I am putting my chassis ground already. Can't the link between the 2 PGs become 2 separate chassis grounds, by joining them in the middle at the chassis?

(I hope you can follow all that... )
