Rogers Project Transformer Magic

July 06, 2015

Progress continues on the Rogers amp…

Transformers are attached as well as the sockets and can capacitors. The reason for the output transformers position is magnetic. This is the position that allowed for the lowest coupling between the power and output transformers on this chassis given the other variables of component placement.

I have I method for determining the positions of the various components with which could fill another book, but again I would rather build. Lets just say that all the components in an amplifier form a kind of "electrosphere" that can work for or against the designers goals. My goal is to make a circuit whose design is symbiotic.

This is the black art that eludes many builders. -Ossie
