How did you come up with using 68K and 400K in the first place? Remember that R=V x I so with both V and I being a small value the R will also be a very small value. Why the worry about 16-18 volts anyway? A simple series resistor of 28.5 ohms ( or 27 ohms close enough standard value) should work FB.

Are you sure there is not a short somewhere like a transistor being latched on when power is applied? Still sounds like waaaay to much current certainly a lot more than 70mA.
