Common Failure Points and Troubleshooting with the Schematic
If resistors R10, R12, or R15 require replacement, substitute the original values with flameproof metal-oxide film resistors featuring a slightly higher wattage rating (e.g., upgrading a 1/4W surface mount resistor to a 1/2W or 1W rated part of the exact same ohmic value). This increases thermal tolerance without altering circuit dynamics. zd95gf schematic exclusive
