I am having trouble wrapping my brain around this power transformer circuit. I must be missing something very fundamental, so I apologize in advance for that.
Can someone explain to me why the center tap on this schematic does not have to be rectified? Also, if the center tap is 0v, how is it supplying power? It appears to be powering all of the tubes except the final 807s. The transformer is a 300v. I'm not sure if that means 150-0-150, or 300-0-300.
I must be missing something simple.
