Input ground is connected with output ground on the board, however, they are run as two separate connections to the board (SG and OG pads)
Yes, that transformer is fine.

Hi Peter,
I am new to this forum and i am interested in building a multi channel speaker system with LM4780 chips. Can you please suggest what should be the transformer that will be sufficient to power up all the chips. Below are the details of the system that i am planning to build.
No of satellite channels : 5 or 7 (60W)
Subwoofer : 1 (120W)
Currently i am on my way to collect some data.
Planning to use 30v-0-30v 5 Amp.
I already have 4 10000uf 63v caps.
Regards,
Naveen P.

It's not an easy answer and the choice depends on how you want to manage chassis build and overall practicality of the system. You may go with a separate transformer for the sub and additional two amp channels and power all the other channels from a second transformer.
Peter,
For those of us who are red/green color blind, could you post separate schematics for the different configurations?
