DIAGRAMS
    Schematic Diagram

 

These are the Manufacturer's schematics and have so many errors it's hard to list them all. For starters the center tap on the wrong side of the transformers. Also the VCC to the transformers is not correct and the bias circuit is wrong. Anyway use with care. Some day if I get time and can find one to go by I will redraw the schematics.
