LED Polarity as Diodes?
« on: February 25, 2016, 03:54:26 PM »
In the Moodring and Deathklaw schematics are the leds positioned with the positive on the square pad and negative on the round pad? I ask because I just finished a Krypton Phasor and had to reverse the led since I originally thought the square pad meant positive? Any help is appreciated, I'd rather not have to re-solder these two, thanks!

I dug deeper and seems I got the answer, never thought about the silk screened image: http://www.madbeanpedals.com/forum/index.php?topic=19432.0

Thank you for that. This is another inconsistent standard. I've found that new world designs have indicator LEDs that tend to be square positive while european boards are square negative. I usually only see LED clipper and LED/LDR marked with the useful round/flat screened image.
