Tube Amplifier Precautions:
1. Tube amp must be connected to speakers before turning ON. Strictly prohibit sending signals to amp without connected to loads(speakers) or the loads will short circuit when the switch is turned 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, pay attention to ventilation and cooling.
4. Do not spill liquid on the tubes while they are still hot.
5. The break-in period for the amp is around 100 hours.
