Re: Center tap fil winding for rect.
Ignore that center tap, just tape the end and tuck out of the way. It's used in some applications with antique directly heated filament tubes requiring a 5-volt supply. They use the center tap with a cathode resistor for minimum hum.  
 
Just use the two outer leads and connect to pins 2 & 8 of the 5U4 socket.
