I built a Killer Bee some time ago and since then Wilkie came up with a mod to replace R14 and R15 with a 100K variable pot. Since I have already built the circuit using a foot switch for boost, can I change the values of R14 and R15 to cut the amount of boost by say 25 to 30%? I imagine this would involve increasing one value and decreasing the other with both summing up to around 100K…? Which resistor decreases and which increases and to what values??
