Hi,
I am building an amp, which will be housed within a metal enclosure. It will be mains powered and I plan to connect the enclosure to the mains earth for safety. The power supply is centre tapped (28-0-28V). On the amp circuits there are several connections that need to go to ground (indicated by the triangle made of 3 horizontal lines).
Do these connections need to go the the earth or back to the 0V?
Also, in general for future reference how does one distinguish between connections that need to be made to the 0V and ones that need to go to the mains earth?
