Hi all,

This thread has been so helpful! I've hit another snag and I'm hoping someone can help. One of my chokes started to smoke when I applied battery power and I was wondering if someone can help me identify the problem? Below are some pics and of course I uploaded the diagram earlier. The choke is attached to C3 and the third pin of V1.

Also I am aware that it is very messy. This is my first homebrew project so please do let me know if you have tips on how to tidy it up. I made the red wires the lines that take positive power from the batteries and the negative is direct to chassis.
