You don't need two in series in each leg unless you want to switch frequencies (but even that only requires pairs of 3.3uF capacitors). For 80Hz you need just a pair of 6.8uF caps.

How big they are will depend on tere voltage rating. You do not need anything more than 100VDC working parts. These are readily available in a 15mm lead pitch:

Ahhh okay I dont know why I couldn't find those but with the part number there it is!

Also I deleted the post you were responding to because I realized what I had drawn up would have the exact opposite effect I was thinking! Thanks for the datasheet!

Would 63VDC be acceptable? I dont think there would be any DC after the output transformer.. is that correct?
