As I said, the 43k is a typo and the design is for a 42k resistor. It probably won’t have a huge effect on the bias, just your wallet.

I had actually ordered 43k/5%/2W resistors, so since they are 5% types they will measure anywhere within +/- 5% of 43k, on the low side they could actually measure:

43,000-5%= 40,850 or 40.85k

And on the high side:

43,000+5%= 45,150 or 45.15k

But note that in each case, that's for a worst-case scenario.

Hopefully my maths is correct, but I'm happy to be proven wrong.
