If you look at the datasheet you will only see connections for single-ended circuits. The Raven is differential, so it requires two plate connections to the transformer. Pins 11 and 16 form the center tap that gets connected to B+, whereas pins 9 and 14 get each connected to one of the plates of the tube.
