DISCLAIMER: Read this FIRST! I take no responsibility for any damage that may occur from using or applying the information in this document. If you do not agree, please stop reading now. You have been warned. DANGER! Disassembling a flashgun is extremely hazardous. Remember that even when disconnected from power and/or removed battery pack, a capacitor can retain high voltage for an extended period of time, which can cause serious injury or death. If you decide to disassemble or repair a flashgun, take all necessary precautions to avoid accidents. Wear protective goggles, thick rubber gloves, and discharge the capacitor before proceeding. Use a 1000-ohm 10-watt resistor to short circuit its terminals for at least fifteen seconds or more. THE SOLUTION! Do you own an old Metz 45 flashgun with a faulty high-voltage capacitor? You can repair it by replacing the capacitor with a new one, but there are challenges to consider. The replacement capacitor may be too expensive, or its length (often longer than the original) may prevent the battery pack from being inserted. I encountered this problem myself and created a project that provides a useful workaround to repair your flashgun using a 40x80mm capacitor. This solution allows you to continue using the original battery pack. To implement this fix, print an extension that will enable you to screw it onto the flashgun casing. Mark and drill two 2.5mm holes on each of the small flaps that help slide the battery pack into its receptacle. Then, use four 3xMA countersunk head screws to secure the extension in place. The .STL file for this project includes supports for the internal latches of the battery pack. These thin walls (0.2mm thick) must be carefully removed with a sharp cutter, taking care not to damage the latches themselves.
