I received the power supply components today, just one question: Are the R1 and R2 470ohm resistor values critical? Unfortunately I don't have any 470 values, and to run some in series would be 5 resistors (220 + 220 + 10 + 10 + 10).

I have 10, 100, 220, 330, and then 1k plus. Hopefully, I can use 330 or 1k, as I'd like to keep it small. But if I need to string some in series, can I get away with just 2 of the above values?
