1st of all, you have made mistake in nomenclature, you have used R1, R2, R3, R5, R6, and R7. Where is R4? In this circuit diagram, you have used 68k resistance at R3. But in your video, where is 68k? There you have used a 1K resistance. You have used two presets of 10k in the video, but in the circuit diagram, you have only one 10k and another is 100k. And in PCB layout you have written 330K (See it), but in the diagram and in the video, you have written 330-ohm resistor.  What is correct? Your circuit diagram and tutorial is easy, but its confusing for the values of the components, so please correct it. And upload it again.
