Benefits of Recapping Your Vintage Fender Twin

• 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 High Headroom & Tight Lows: Fresh filter sets stabilize high-voltage power rails, preserving the legendary ultra-clean headroom, punchy lows, and crisp transient response the Blackface Twin Reverb is famous for.

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