I made some progress on the tuner with a working set of circuits installed in the chassis.
This then exposed a bunch of problems that need sorting but at least it works in a fashion.
I don't mind any comments or thoughts about the design and the way syncrodyne or direct conversion sets should work.
The reason why the Superhet system stayed with valve technology only becomes apparent when you try and make a valve direct conversion ciruit work in a practical sense!

Cheers, Fred.
