100 ohms did the trick. Now I have 3.37V for the oscillators

Maybe you needed 63 Ohm for spot on awesomeness

Hi,
I'm going to build some UltraBiBs
+-15V, 500 CCmA and +5V, 300 CCmA.
Should I populate 5V boards with red LED's and +-15V boards with green LED's? Or can I have red on all boards as specified in POM-file?

regards
Micke

Red in all is fine. The most likely one to have marginally less intrinsic noise is the red as well. But due to C2's filtering action any small differences would get swamped. So if you want green or orange or yellow for aesthetic reasons in >5V out builds feel free to also select them. Say green LEDS look well with Nichicon BP green capacitors nearby. Or the rest of the build's circuit like DAC etc. has greens their light color you want to match not to have mixed ambient light escaping from box's top vents in the dark. Avoid blue and white though which are significantly noisier and have high Vf.

I will build them over Christmas holidays, so red and green will be excellent. With some luck maybe my wife sees it from the viewpoint that I help with Christmas decorations

Thanks Salas
