RB-1090 bias setting

[tanwn]

I understand that Rotel recommends a bias setting of 5mv across TP1,2 for rotel rb-1090. Mine is the all black color amp. Can someone tell me whether the silver and black version has the bias tweak differently by rotel? If so what are the values? thanks.

There's no reason for it to hae different biases, the color is only a plastic front cover... that's it. Now the older vs. newer models that have different binding posts *might*. But basically it's all to be the same.
