RE: Purpose of these Caps?

G.E.C. developed and patented this circuit (patent #487953) as a driver for Class B output stages. They called it a cathode coupled bridged transformer. The capacitors are there to short circuit the transformers leakage inductance which they claim is the main source of distortion and the bad rep. of Class B amps. In the book "An Approach to Audio Frequency Amplifier Design", originally published by GEC in 1957, there are a couple of Class B amp designs and a high power AB2 design that use this circuit.
