I'm repairing a used Olympus Microscope (Model BH-2 BHS). The circuit board looks like someone tried to repair it and a diode and another part are missing. I tried to find a circuit board but haven't found one. Do you know of any businesses that does circuit board repair for reasonable prices? My hands are not steady enough to repair circuit boards. I would like to replace the circuit board but I can't find a new one.
