Repairing a Western Electric 555 driver
However, if you choose to proceed with the repair, the first step is to carefully inspect the driver and identify the specific issue. In the case of a burned-out voice coil, as suspected by one individual, it may be necessary to source a replacement coil. These can be costly, with a single replica voice coil priced at $625.
Before attempting any repairs, it is advisable to gather as much information as possible about the driver's design and construction. This can include studying line drawings, reverse engineering, and examining static pictures that showcase the design, construction, and internal components. This information will be crucial in understanding the inner workings of the driver and guiding your repair process.
The repair process itself can vary depending on the specific issue identified. For example, if the voice coil is indeed burned open, you may need to carefully disassemble the driver, replace the coil, and then reassemble it, ensuring that all connections are secure and properly configured. It is important to note that even tiny changes or marks left during this process can affect the performance and value of the driver.
In addition to coil issues, other components, such as the diaphragm, may need attention. Creating a diaphragm at a DIY level can be challenging, and it is recommended to start the design process from the diaphragm and work down to the motor structure. Mylar is suggested as a suitable material for the suspension system, as it is easy to source Ti diaphragms with a mylar surround.
Overall, repairing a Western Electric 555 driver requires a combination of technical knowledge, careful execution, and attention to detail. It is important to proceed with caution and seek professional assistance if you are unsure about any aspect of the repair process.
