808 manual snare revision questions

hi I have done the snare revision in the tr808 manual

My question is what sort of cap do I replace r127 with I have used a non polarised 10uf electrolytic

Should I use a polarised one if so which direction does it go in ?

My snare sounds better but now my clap is weird

I have not yet changed r311 as it is in the rimshot section and it says change it from 330k to 100k and at the moment it's 10k as per yocto build guide , what should I do

Cheers Ciaran

R311 is a typo, if you lok at the revised schematic:

R131 changes from a 300k to a 100k.

I'm going to put a trimpot in mine though, as I can only get down to 280mV
