Yes, you need 1000 volt caps across the audio output xfmr primary because there can be inductively-induced voltages across the transformer that are higher than the DC voltage, especially if the speaker is accidentally disconnected. I do believe there are 1600 volt mylar caps but cannot recommend a source. Ceramics would probably do the trick though.
I have seen 1960's equipment that uses axial caps and runs one lead down the side of the capacitor on a circuit board, personally I don't think it looks so bad. I have never seen radial-type modern mylar/polystyrene caps.
