Hi
I am nearing completion of my G7 project.
PSU and mic pcbs are finished and now I am working on the mic body.
I have been reading extensively on the earthing and wanted to check I have understood it correctly.
1) Safety earth in PSU connected to chassis - as per standard safety practice
2) All other earths connected at the mic body - best accomplished by connecting pin 1 of the 7 pin xlr to the mic body.
3) Heater 0v ( pin 7 of mic xlr ) also connected to this point
4) HT 0v ( pin 5 of mic xlr ) also connected to this point.
5) No other ground connections from the PSU board or PSU xlrs to the PSU housing.
In practice how do people connect the earth point to the mic body - solder tag on one of the baseplate screws etc ?
Cheers
Pete
