Important Notes

1. The tube preamp operates in a Class A amplification state. For optimal performance, it's recommended to use shielded wires for the signal to prevent potential leakage or noise.
2. High-fidelity sound boost can be freely adjusted with a three-setting wave switch:
• Left position: "Hi-Fi"
• Center position: "Boost 1"
• Right position: "Boost 2"
3. Using unshielded signal lines or poorly filtered power supplies can cause noise. It's advisable to use shielded wires and a clean power supply for testing.
4. The tube buffer amplifies about 5 times. The pre-amp is designed to connect between the audio source, the pre-amp, and the power amplifier. Any noise from the audio source will be amplified, so a high-quality audio source is recommended for testing.
