What's with the 33k resistor? It's value isn't a simple rounding of the calculated value 31.6k

    The 47k is seen in many places. Now, today, I know the reason! Thanks a lot.

    hmm, that orange looked nice. At the Maplins close down sales, I stocked up on 330 ohm & 4.7K for LEDs & pull up resisters.

    I like 47 and their variants esp in head amps.

    There r def 2 types of people that do this. Him who has to know b4 he touches anything and people like me that go close enough. Solder it down, volt check then hope it don’t smoke and turn it on. They get mad every time close enough is good enough. 😂. But at least this was very detailed and explained what and why well.
