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.
