Power transformer star ground
Hi I have been referring to Aiken Amps article on star grounding and he says in the addendum #3:
"You have to run the centre-tap of the power transformer B+ winding (or bottom of the B+ winding if you are using a bridge rectifier) directly to the first filter cap without going through the chassis..." I have decided to use this method for my power stage grounding and I am using a bridge rectifier and have no centre tap on the transformer. Am I supposed to take my transformer ground wire from before the rectifer (AC) or from between the rectifier and the first cap (DC)? Thanks |

You would ground the DC negative side. Never the AC.

Thank You! That's what I suspected, but when aiken said the wire goes directly from the transformer I got confused!

That would be true if you were using a full wave circuit which involves the center tap of the HV winding.
