I am completeing my first Simple SE build. The Box is wooden so I know I will have to run ground straps to all of the transformers. I do intend to use the cathode feedback switch which means that my OPT secondaries will be tied to ground via the board.
George states in his instructions that with CFB to use the input jack ground to bond the circuit to the mains ground. A single point eliminates ground loops which is makes perfect sense. However, my inputs jacks are on the far corner of the chassis. Would there be any difference in bonding ground to another point on the board. (Providing it is the ground plane of the board and not B+ etc.). This would help keep the wiring clean inside the chassis. I can't see that there would be any difference but would like some confirmation of my logic. Thanks

George's suggestion is based on the premise that you are using a metal chassis. Since the input jacks are easier to install without having to insulate then from the chassis, why not make that the grounding point? Since you have a wood chassis, you can do whatever you want. They key is to maintain a star ground. A circuits should be grounded at single point wherever possible. In the case of the PCB, just pick one of the grounds from the input wiring or the jacks themselves and run a wire between there and your selected grounding point.

Thanks,
You confirmed what I thought. I really wanted to make sure that I didn't miss something in the PCB that makes the input jack preferential to another point on the board.
