[...] > "Ole Bob" Thanks for the information. The current density at the anode is 12.6 / (5 * 8) = 0.315 mA / sq. in. A 3/64" dia rod has a circumference of 0.046875 * pi = 0.147 inch, so the current density at the cathode is 12.6 / (7 * 0.147) = 12.2 mA / sq. in. This is a bit high. Unless I goofed somewhere, I'd be surprised if the LM317 goes into current limiting right away. What is the initial voltage across the rods when power is first applied?
