I am confused again. Reading the Radiotron 3rd ed. It appears to say input voltage rating of power transformers should be made with the secondary fully loaded. What am I doing wrong if I may ask. Regarding Guenievere; I have printed out three different filament schematics. We are using the filament windings on the power trans; not the radio shack 12v trans is that correct? And I thought Golf was hard.
