X-amp in 1974?

Looks like an X-amp of sorts. Lo-fi though.

Nice example of "prior art".

I don't see why is so lo-fi. Not for the time at least.

Definitely qualifies, as does the Hadley.

What does "prior art" imply?

Was it drawn up but never implimented?

And here is the article: http://www.schematicsforfree.com/aud..._Amplifier.pdf
Looks like a very neat DIY-project.
Could it be upgraded to perform better in the higher frequency
ranges? One could probably make a nice amp if 50Khz could be achieved.

My initial experience with X amps at this
level of complexity put me off on them for quite a while. It has
to be a pretty simple topology for the X to work with any
decent bandwidth.
