Hey guys. I've studied Rob Robinette's mod section re NFB switching and I think I get it. I have a 5f1 I built a couple years ago and I'd like it to be grittier. I built it from the BYOC kit (original layout attached). If I wanted to switch between the stock value and some other pre-set value, is this how I'd place the switch? (Or an on/off/on if I wanted a no-NFB option). I see tons of guys talking about the mod but no one shows it in place in a 5f1 layout and I'm always hesitant. Any suggestions on a good value for the X resistor? Is no-NFB usable in the 5f1, or is it too much gain? Thanks!
