NB:
I haven't decided the value of the 470R sense resistor yet, I'm not sure if it is taken from board measurement of the B+ or calculated from the B+
I'm not sure how to put 2 resistors between each CCS bottom and M1 source if there is instability, given that both the CCS's are joined, surely only 1 resistor will be possible here?
