Vacuum tube amps the use of attention:
1. Disable output short circuit and output load, before you start you must first connect speakers or headphones, the best is always keep them connected,
2. Start with minimal volume,
3. The supply voltage should be stable, with the use of conditional HiFi clean power for better protection and sound,
4. When the vacuum tube amplifier operating temperature is high, pay attention to ventilation, not to touch hot tube,
5. Do not put water on a hot vacuum tubes,
5. Do not put water on a hot vacuum tubes,
6. Boot and shutdown interval of 5 minutes,
7. Do not over 6 hours of continuous work,
8.6 ohm speaker connected to the 4 ohm, 8 ohm interfaces are available,
9. vacuum tube amplifier sound 40% depending on the power amplifier tube quality, 40% depends on the quality of output transformer, 10% depends on other electronic components quality, 10% depending on the manufacturing process,
10. power supply voltage can be free custom (please consult).
