I have a small CRT display and driver board that I have extracted from a broken camcorder. The driver board requires 4.75 volts DC for power. I don't have any way of providing this voltage from batteries, so I need a voltage regulator, or converter or a transformer that will output 4.75 volts. I would prefer that the input voltage of the converter/regulator be 12 VDC, but a lower or higher voltage is acceptable. Any help is appreciated.
