I have 2 of these bridges. In less then a year the circuit board that makes the lights blink did not work on both bridges. The bridges were in warranty and Midge replaced both of the circuit boards. The part niumber for the circuit board is AG0000062 and as far as the price I am not sure but maybe around $15.00. I am now running the boards at 10 volts ac and have installed heat sinks on the ouput transistors. The outputs now run with out any heat build up
Thanks Bob K.~
