The resistor feeding the LED at the 5-volt output should be 470 or 560 ohms.
I'll try my PC817 optos to see if 0.8 volts turns it on.
 
Woww no primary snubber BUT what is the OP's question ??????????

Ohh I see, it's in the form of a vote.....

Let's start with where on earth did you get the circuit ?
 
What material, diameter and length of the core?
and the Asterisk(*) in the image says there is a video, where is it? And how clueless was the anyone to mistake a 260k ohm for 2.6 ohm
