Hi All, I need help! I just got given to me a really nice graphic equalizer with real time spectrum analyzer, only problem is, it is missing the power transformer which has two voltage input sections! As I have no schematic for this, and have not found any info on the net I am at a loss to find the voltages which powers the display board I guess that it is around 5 volts but I would hate to fry it before trying out the forum! Any help would be really appreciated. Thanks Nick
