Dear Colin,
I am pleased you like the content of my old site. I am sure a lot of it will reappear as time goes bye.
Here is the Tweaker circuit. Earle was happy for me to publish it. It is being revised all the time. My mono amps will have some changes to the one shown here. I have only shown one power amp channel to help cut down on image size.
Valve sockets arrived today so one step closer to starting.
