Wiring ground switch for a SUT

Cinemag CM-1254 SUT build thread

I'm hoping that the lucky owners of the CM-1254 SUT will group buy use this as a build thread so all information can be consolidated here for future reference.







This is a question I have on the grounding scheme to use on my CM-1254 SUT build.



I hope the attachment came in. This is my plan so far.

Switch position (1) Ties input grounds to chassis ground


Switch position (2) Off


Switch position (3) Ties both input and output grounds to chassis ground


The Faraday shield will be tied to chassis ground as well, the transformer bodies will be tied to ground as they are mounted on the enclosure metal box.



Am I missing anything here?


Thanks

Just added a revised schematic that is very similar to the CM-1254
