Hi,

What is the proper way for earthing in a bridge-rectified power transformer without a center-tap ?

Thanks.

metebalci,

The following assumes "normal" tube circuitry with a negative ground.

There are 4 connection points in a bridge rectifier. The trafo gets connected to the 2 points that join cathode to anode. The point that joins 2 anodes together gets grounded. You take the B+ from the point that joins 2 cathodes together.

Ok. So, connecting the earth of main line to the ground point of bridge-rectifier is safe.

Thanks.
