So your saying they are using Pulse Width Modulation Rodney? That would make sense....... and be much more efficient.

O.k...... now for all you E.E's that, much like me, had to chime in........

Mike, absolutely correct...... I use impedance and resistance interchangeably when refering to DC circuits. However by the letter of the law you are correct, as is JNorton who PM'd me with a similar correction

Montague, That would make sense and have been my guess as well. I didn't mean to say that the pot (Knob) on the power panel dropped the entire 10 to 11 volts. Although I can see how my post implies that.

Now I know where the E.E's of the world like to hang out.......
