• 2 x 220K - 1W Resistors: Voltage Balancing / Bleeder Resistors

Benefits of Recapping Your Vintage Fender Amp

• Eliminate Mains Hum & Noise: Original 50+ year-old filter capacitors lose capacitance tolerance and leak DC voltage, introducing frustrating 50Hz/100Hz background hum into your signal path.

• Restore Tight Low-End & Clean Headroom: Fresh filter sets stabilize high-voltage power rails, preserving tight bottom-end punch, fast transient response, and pristine clean headroom.

• Protect Output & Power Transformers: Shorted or dried-out power supply capacitors put heavy stress on rectifiers and transformers—leading to catastrophic component failures.
