Road Rage - thinking out loud...

[bramofon]

I just got the Road Rage PCB and got it up and running. I'm using it to provide 18v to a clean boost pedal I came up with. The pedal includes 2 LED's to indicate boost and mute. I originally had them wired with 330R 1/4W resistors when I was working with 9V, but I disconnected them when experimenting with 18V. I forgot to get the needed resistors for the LED's. I figure they should be about 820R and 1W, which I don't currently have.

That was the story, here's the question. I'm wondering if placing the LED's BEFORE the Road Rage. I am using 3PDT switches so the LED's are not messing with the audio (so to speak). Would that work? Is it a bad idea? Can I just hook the LED's into the source 9V or will they need to be isolated somehow?

If you have any input, I would appreciate it. Let me know if I was unclear about something.

820R seem too low for a led, i think you should use a 2.2k-10k for that

Just take the 9V off of the auxillary 9V tap on the RR (assuming you're using the new one).  You could also take it before the board, but it wouldn't be as clean.

820R is way too low for the CLR, especially if you're using waterclears.  I use 2.2k, and I can illuminate the entire man cave with my pedalboard....

Thanks for the suggestions. I was using an LED calculator but it makes sense that it was designed to give maximum brightness.
