Sound is a bit more tricky, there's no audio preamp stage, just crappy quadrature detector straight into a 6BQ5... Will need to add a preamp somehow, maybe a 6C4?

Use the luma of S-video. Simpler and much better than trying to filter chroma out of composite.
A 6AV6 as an audio driver may be better, but you'd need a volume control in front of it. Else it may distort.
