Part 2/6:
A key step in the restoration process involves replacing aging electrolytic filters with modern equivalents. These capacitors, crucial for filtering power supply fluctuations, are identified by their polarity markings—an arrow indicating positive and a minus sign for ground. The technician notes that the replacements are smaller than the original capacitors but serve the same purpose effectively.
The procedure emphasizes attention to detail: ensuring correct orientation by matching polarity markings, leaving the original capacitors disconnected but physically in place, which allows for possible future restoration or troubleshooting. Proper handling, such as applying a light coat of WD-40 to mechanical parts before reassembly, ensures smoother operation and ease of maintenance.
