ADK TC Mod Service
ADK TC series mics are tube cardioid microphones originally packaged with various accessories. An upgrade service replaces components to improve sound quality and reliability.
- The stock 12AX7 tube has very high gain and high distortion, limiting headroom.
- Replacing the tube reduces output level by 6dB and lowers harmonic distortion by up to 20dB.
- Replacing the output capacitor with a high-grade film capacitor improves sound quality and reduces failure likelihood.
- Replacing the input capacitor with a polypropylene and copper foil type and ensuring proper soldering improves reliability.
