Features:1. It adopts SANYO high precision chips in Japan and is of excellent stability and CD recognition.2. Servo circuit adopts Philips SAA7824 chips.3. It adopts PCM1794U chips produced by BB4. It adopts high-quality multilayer filter circuit and can validly clear digital signal, to bring you music signal output of high fidelity.5. It adopts two 6N8P amplifier circuits with excellent acoustics and strong driving force together with high fidelity operational amplifier output. The two pair is alternative.6. It adopts coaxial digital signal output (Can connect with audio decoder)7. The auto circuit is manufactured by Philips (MKP) no polar capacitor, popular audio special electrolysis as filtering and metal resistance of high precision.8. Power transformer is made of silicon steel sheet (0.35mm) special for audio frequency, and oxygen-free enameled copper wire of high tension in special wiring process. So the machine is with less electromagnetic interference, strong driving force and transparent, powerful acoustics.

Tube amp must connect with speakers before turning ON. Strictly prohibit send signals to amp without connected loads (speakers) or load short circuit when the switch is ON.2. Too high or too low power supply voltage does irreversible harm to the amp, preferably less than 5% of the specified voltage. If your mains voltage exceeds this value, often best to use with the AC power supply.3. Temperature is higher when tube amps working, placing attention to ventilation, cooling.4. In the boot or just shut down for a period of time (within 30 minutes) Do not spill liquid on the tubes.5. You should take about 100h times to operate the amp. RUN-IN to the amp gives its best and stable sound.so during the first 100h use time the sound maybe is not the best, you can also use your own run-in method.
