Does anyone know what Quad used for C1, C4, C6?

Was it X7R, Z5U or maybe C0G?

Either polystyrene or C0G.

They probably used a cheap ceramic, I doubt they would employ a high quality C0G/NP0.

I should clarify. That's what I'm recommending when replacing. I have no idea what Quad would have used.

I like to use C0G here, but before I do just want to check is it possible Quad use C0G originally?

Well of course it's possible, but, as CBK said, they probably didn't, on cost grounds. However I have no information on it one way or the other, and no 909s on the bench at the moment to look at.
