I have almost finished my C12 clone, just need to connect the right capsule BUT there is one thing still that's unclear to me: The Big resistors.

Oliver Archuts rewrite of the C12 schematic calls for between 200M-1G bias resistors. So, this might be a stupid question, how exactly should i choose the best value?
 
Thanks Jakob!

I guess i'll go with 250M then. Now I have 1G ones installed because those were the only ones i happened to have at the time.

So 250M should be the resistor when using CK12 capsule then? (I'm installing Tim Campbell capsule)
