What effect did the power supply have on the immunity? It's difficult to know with no data what a simple analog power supply would do. One would certainly need to know that in order to determine whether a filter was feasible and the optimum solution. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
