About A-6000 

A-8000 hi-fi amplifier, a masterpiece designed by Mr.Guan, has got a lot of praise at home and abroad. Soon Mr.Guan got a fresh 

idea of building a mini hi-fi amplifier to continue the beautiful outlooking of A-8000. He intended to make 6N3 serve as pre-amp 

and LM1875 power module as amplifier. Both these two items have got high recognition by shrewd audiophiles. 

Although some other IC models such as TDA2030 or TDA 7000 are much cheaper but Mr.Guan still refused compromising chose LM1875 firmly. 

We can be assured that no flaw will exist in a master's great work.

Tube Amplifier Precautions:1. Tube amp must connected 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 time to operate the amp.RUN-IN to the amp gives it's 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.6.
