I can't get it working. I'm trying the left channel with only one led, trying to start small. Everything seems to be connected correctly. I'll list the components I'm using, maybe one isn't correct. 35v 10uf cap, 2n3904 npn, a 22 ohm resistor, 150 ohm resistor, and a IN4003 diode. Is there any common noob mistakes that I may be making ? Thank you for your time.
