RE: GZ34: getting too much voltage drop
Posted by sideliner on February 11, 2017 at 14:05:48:
This is correct and it's not my point of contention. It's of course either 0.9x taking it from one end of the transformer to the CT or 0.45x taking it from end-to-end. My point is that at the input of the filter - be it choke input or cap input, the VAC RMS is equal to the RMS at the secondary minus whatever drop occurs at the rectifier.
In this case the math simply doesn't work out to justify the 290V at the rectifier's cathode as shown on the attached schematic. That's why I suggested that the OP confirms that the no-load voltage at the secondaries is as it should be.
