Audiophiles have fun with welders and motors, and are willing to study new audio circuits and speaker structures. They have deep electronic production and home appliance repair bases, improved circuits, corrosion of circuit boards, and even home computers as sound. Classes come to the machine, although they dare not make a big move, but overclocking the CPU is affirmative, but also for the power supply and sound card is always worried, often do some to increase the filter capacitor, or remove the sound card amplifier part of the work. They are familiar with fever electronic components such as several Jane, Sanken amplifier tube, Toshiba field effect, AD op amp, Solen capacitor, Rubycon electrolysis, ALPS potentiometer, DALE resistor, and of course, Twilight tube, Dahongpao resistor, etc. Even more clearly than a few sets of noble suits.

Their hands are always idle, the welder's enthusiasm exceeds the date of the lover, once they have a new work, even if only a small adjustment to the circuit, or add a little sound-absorbing material to the speaker, also Publicize and inform your friends to come and listen. It is even more love-hate and mixed with the newly added equipment. I always feel that my level is higher than that of the senior audio engineer of the international famous brand audio manufacturer. At the beginning, carefully keep the seal, carefully open the cover of the machine, and appreciate the overall structure, circuit characteristics and components used. Immediately there will be their own unique insights, complaining that the manufacturer's materials are not enough to have a fever. Finally, I couldn’t help myself, I couldn’t control my hands and feet, and I still couldn’t control whether I needed a warranty. Take the screwdriver, attach the soldering iron, and rummaging through the cabinet to find out your own fever components.

Wait a minute, still calm and excited, or brew a pot of good tea, start the operation, first weld the components that you think are "smelly meat", replace it with a fever boutique, increase the power filter capacitor while not forgetting Parallel small-capacity CBB, while operating from time to time, the skunk manufacturer's circuit board design is too crowded, so that some boutique components need additional pins to install. For the power amplifier, always want to adjust the quiescent current to the radiator and also have a high fever. Hey, often for this reason, the original power amplifier tube of the manufacturer can not withstand high fever and die. What's more, in order to save space in the equipment, there is no need to use the ready-made DAC decoder. It is necessary to buy the motor board provided by the manufacturer. After the board gets the hand, the first thing is to "money board", in order to test yourself. Whether the soldering iron is still easy to use, whether the multimeter is still accurate, and its own welding technology can make itself satisfied.

I can finally listen to it, and I am not afraid of others laughing. I can't wait to let my love machine put on my clothes. The chassis is still open. The speakers are still a few screws, the soldering iron has the temperature, and it doesn't matter whether it is late or late. Friends, take the comrades out of the warm heat of the nest. Don't wait for friends to come, rush to start the audition, let friends evaluate their masterpieces. Of course, the neighbors are often dissatisfied with the door to remind or knock on the heating pipe to protest that it is a common occurrence. At this time, I had to complain that I had earned less money. I began to imagine that if I had a separate villa, I would be fine.

Their feet can't be spared. On a rest day or on a business trip, they must go to the component market. When buying components, they always want to buy the best things at the lowest price. After the transaction, they don't forget to let the boss take a speaker. Line or a small audio plug. Also because of the lack of silver bullets, visiting the second-hand market is the greatest pleasure, because there is indeed gold in the market, originally to save money, but also the name is imported, resolutely put an end to fakes! But the harvest is still quite large If you are lucky, you can use the 1/3--1/4 price of the new product. When the price is low, the equipment is said to be useless. I also pretend to kick the two feet. Once the door of the store is out, I will wipe the footprints with the handkerchief just sent by the lover, and hold it tightly like my own child. In my arms, my heart was secretly glad that the performance was just successful.

If you visit his home or dormitory, a cup of wolf, the table, the ground is full of tools and components, due to several days of welding machine, even the instant noodle bag is still on the ground As for sometimes because it is too focused, it is sometimes happening to put a white hot iron core in the mouth as a cigarette. It is clear that he is lazy and unwilling to clean up the room. He also argues that this arrangement is to improve the listening environment, increase the sound absorption medium, and reduce the sound reflection. It is really reasonable to think carefully.
