Earthing Questions

Buddie · 26th October 2010, 07:37 PM

Hi all!

I am finally putting my first amp into its case and I want to make sure I connect the earth pin of the wall socket correctly. From what I have read, I think I should connect it to a point on my chassis with a screw and to GND on my PSU. My PSU has dual secondaries and two bridge rectifiers. Is this the correct scheme? I want to be safe.

Thanks!

fig 3.18 has omitted the diodes shown in fig 3.17. Do not omit these high current diodes, if using the Disconnecting Network.
