To follow up on my previous comment, R2 and R6 on. CTR-30B should be swapped. R6 should be a 2K ohm resistor and R2 should be the 330 ohm resistor.

This is a fun little holiday project for someone with average soldering skills. It will take a little longer than you expect, but the result is good. One issue I'm having is that the green LEDs on CTR-30B are very faint compared to CTR-30A. I cannot figure out why this is, but when I check the video associated with this product, it looks like the same green LEDs are faint in the video as well. For that reason, I believe there might be an issue with the circuit. Perhaps the resistor values are incorrect. That said, the project still came out well.
