I’m using the Weber WSE15. Grey is 16, Yellow is 8 and those are the only two i’m using (don’t have a multi tap rotary switch yet, only a double throw).

it is curious that i am reading ~1.5k on the feed back resistor since it has a 1.5k right next to it shunting to ground, but I kept remeasuring it since I didn’t believe what i was seeing – and i was measuring it directly across it’s own leads (amp off, not on).
