Collosalus: alternatives for 51pf at C23?

[Marv Mod]

I'm struggling to find a 51pf cap at position C23 to finish my Collosalus with. I can get a 47pf and 56pf no problem - would these be acceptable alternatives? If so would one be more preferable over the other?

Any help would be greatly appreciated!
Many thanks,
Jeremy

Either one should be fine. It's just shunting very high freq's (like RF noise) to ground.

Thanks mate, I'll get a bunch of 47s and 56s - chances are some might be nearer to the 51pf mark on the multimeter so will go with the closest match.

Cheers,
Jeremy
