Cap Kit Notes
• Use 105°C rated replacements (Panasonic FR, Nichicon UHE, or equivalent) for improved longevity.
• Replace caps at rated or higher voltage — never lower.
• Observe polarity — the negative lead is marked with a stripe on the capacitor body.
• Values extracted from schematic images — verify against your specific board revision before ordering.
