I looked further into the datasheet and I see that somehow the CP still allows up to 90mA (from what I see). So If I want 85mA it says I need a 229ohm resistor on the chip. So since there is two per side does that mean I need replace all 4 resistors (2 1k and 2 trimpots) with 114ohm or just short the trimpot and run one 229ohm per side?

Also, it would have to be a 114ohm that holds over 2.5w?? Or how much wattage?

Thank you!
