There's a project I want to build that I saw online a few years ago, unfortunately the poster never updated his progress, I was hoping to get some insight here as to how I might go about constructing this project.
The project in question being explained here http://tubelab.com/articles/ideas/solid-state-opt/
As far as I understand it splices up the signal amplitude at a constant frequency outside the audio band and then unsplices it at the other end of the transformer. What I don't get so far is how the displayed circuit on the left is supposed to function because to me it looks like it will effectively just act as a high frequency source follower on the load. I don't see how you can make transistors act as pure switches in this way.
