I’m new to building pedals and I’m currently working on the Ratt Deluxe kit.
I am aware that LED lights are polarised but I’m having trouble finding information on the leg orientation for both D3 and D4. Can someone please tell me where the anode and cathode are placed for both of these?
The LED has a flat side that indicates the cathode. The board shows the flat side on the silkscreen. I invite you to take a few minutes to read the guides posted on this site. It covers many valuable subjects.
