If I wanted to drop closer to 24 ma what would I change the bias resistor to ?
The current resistor (R29?) is 15K
The circuit board is revision D.

Thank you.

I would recommend putting in a 50k trim pot in place of R29 as mentioned here:

I thought about that , but I don't know if there's room.
My board is a different revision than what that shows.
R28, and R29 are side by side.

Well then what you could also do is clip out the resistor but clip close to the resistor body leaving enough of the leads showing, clip on some of those alligator test leds then try a few resistor values maybe a 20k; once you find the correct value solder it to the original leds.

Will do. thanks for the help.
