- Repair or Replace Electrolytic Capacitors
new
- For low voltage applications, like cathode bypass capacitors, most vintage types have an axial configuration, which is less common today but still available. Electrolytic power supply caps likely constitute the single worst liability in old audio, radio and test equipment.
