Hi,
I am building one of the Audiosector LM4780 kits with each chip in stereo mode with one transformer and one rectifier board. Reading through all the posts I could find on grounding I am still confused as to how to do it with my configuration. Should I be using a version of this scheme?

I have isolated the chips from the heatsink as recommended but don't know where to go from here.
Any help gratefully received as I'm so close now to getting the amps working and can't wait to hear them,
Mark.

Thanks littlerick, I assume chassis ground is the pad marked chg on the underside of the boards. Am I right in thinking SG on the boards is the input ground from the RCAs and OG is the output ground to go to the speaker connections? I notice they are all connected together anyway when I test with a meter.
