Quoted from ChrisHibler:If I may ask, there looks to be a 750 ohm and a 180 ohm resistor, assumed to be in series with the LED and power.
Why two resistors instead of one 1K resistor.

One is for the voltage drop for the LED source. The other is the “bypass” resistor for the SCR load to eliminate flickering. Same concept as my adapters or Altek driver boards.
