hi,
It is possible to connect a series power resistor in the +14V line before the regulator.
For example if, the the +14V was regulated and you required never more than 250mA, you use a 20
hm: 2Watt resistor to drop from 14V to 9V.
This would mean the Vreg would have 4V across it at 250mA, which is about 1Watt.
Using a 32R 3Watt resistor would give a drop of 8Volts, that is 6V into the Vreg.
That is 1V across the Vreg at 250mA, which is 0.25Watt for the Vreg.
If you do it this way I would suggest that the smoothing cap is connected between the junction of the resistor and the Vreg, to 0V.
