I have altered my original post here as I've come to the conclusion that on my board, who ever assembled it has reversed R2 and R7 I shall reverse their position and report back as to whether it works or not.
EDIT.
Have now reversed R2-R7 as per the schematic and can report it all works ok.
Er yes I know I'm fully aware how to read resistor code,what does that have to do with R2 and R7 being in the wrong place on my board? I assume this is aimed at me?
I am only pointing out that R7 which should be 470 ohm and R2 which should be 4700 ohm seem to have been swapped on my board regardless of terminology.

Thank you.
It's good to know that the design as written (or with the resistors reversed) works.
When I run into issues I now know it's my implementation rather than a design error.
