pork barrel question

[shay1510]

hey guys,
Did you ever get something working when you know it realy shouldn't be?

I've modded my pork barrel so I would be able to choose between R39 (4.7k) and 22k (depth mod described in the pdf) using spdt.
Then, while trying to fix my ticking problem, I've removed the 22k resistor+wire and I was left with what you see in the lower image. The big surprise here is that the mod still works! I use the switch and have a greater depth added.
Can someone explain to me why/how does it work?

my guess would be that led wasnt matched with a resistor properly and  might of been clipping.
what do i know ? im just a beer drinking donkey !
