Siheyuan: Pioneer in anti-corruption, fighting against evil!

There were currently 0 skill points remaining, which he used to upgrade his electrical appliance repair skills. 40 points were allocated to this category, and the skill level increased rapidly: -. Then, a strong reaction like being hit by an electric current appeared on Li Aiguo's body, and a large amount of knowledge and memories that he had never encountered before flooded into his mind.

The working principle of electronic equipment, the connection method of internal circuits, the principle of electromagnetic interaction and its application, various problems and troubleshooting methods, as well as various problems and solutions that may be encountered, these complex information were presented in his mind in an extremely intuitive way, allowing him to master them almost instantly, as if they were integrated into his blood.

After quickly reading the newly acquired information, Li Aiguo's eyes suddenly opened wide, and he was filled with surprise. This time, the system generously gave him a huge help. He mastered more than ten comprehensive skills including TV repair, radio repair, and other home appliance repair. With only 40 skill points, his radio repair skills can be comparable to the level of the top after-sales service workers in the industry. If there is a concept of after-sales service for radios, then this skill is definitely the best in the industry.

When Li Aiguo was about to throw away the ten-yuan "junk" radio, someone called out to him, "Xiao Zhang, let me try."

Zhang Erpao stopped in his tracks when he heard this. "Big brother, I tried my best to operate the camera this morning, but still failed. Forget it, just deduct 10 yuan from my salary this month." He looked hesitant and helpless.

However, Li Aiguo explained: "Actually, if the wires inside the radio are loose, tapping can sometimes help. This means that it has been repaired many times and finally abandoned, so it is difficult to restore it to working condition even if you try hard. How about I try it myself?"

Zhang Erpao was shocked and asked, "Big brother, can you repair the radio?"

He replied softly, "I just read more."

Although this conversation was brief, it was full of trust and support for Li Aiguo's skills.

Zhang Erpao and Wang Dagui often saw Li Aiguo reading various books all day long.

The contents of these books vary greatly.

They include profound ideological and educational monographs, as well as handwritten materials similar to "Guide to Flower Appreciation" and even knowledge manuals on how to care for livestock.

It's not surprising to occasionally read some tutorials on repairing home appliances.

Because "every profession has its own expertise", if you want to repair a radio, of course you need professional tools and equipment.

Fortunately, junk stores are like small grocery stores where you can find all kinds of strange and rare items.

So, Wang Da Kui quickly found all the equipment he needed, such as multi-function measuring instruments, screwdrivers, welding pliers, solder wire, magnifying glasses and more than ten kinds of professional tools.

"Brother Aiguo, as long as we successfully repair this machine and sell it, we can sell it for at least 500 RMB, which means a high profit of five times."

Wang Da Kui said with anticipation.

"Whether it can be repaired depends on the cause of the machine failure. If there is a problem with the core component - the electron tube, it will be difficult to achieve the goal."

While speaking, Li Aiguo skillfully turned on the radio.

For those old radios equipped with vacuum tubes, they usually do not need a circuit board to work properly and have a long service life; failures are mostly caused by problems with the vacuum tubes or capacitors (usually located next to the cathode).

After a careful inspection, Li Aiguo showed a relieved smile: Fortunately, the radio only had a problem with the power amplifier tube, and the repair method was just to reuse the bypass capacitor in the electronic components.

"Come on, Erpao, prepare some solder."

After putting down the multi-function instrument, he took a towel and began to clean the dust and dirt inside the radio.

At this time, a slightly greasy figure approached, with a pair of shining eyes. "Li Aiguo, you can repair radios?" The one who spoke was "Uncle Liu" from the old house next door. He was carrying a few empty beer bottles and was ready to go to the scrap stall.

"Uncle Liu, this is purely my hobby. Come on, Zhang Erpao, put your things away!"

After responding casually, Li Aiguo lowered his head again and concentrated on cleaning the dust around the parts.

Every speck of dust will affect the final welding quality.

"Uncle Liu" who received the bottle of wine from Zhang Erpao received three cents of pocket money. After putting it in his pocket, he did not rush to leave. Instead, he squatted aside and watched the welding process attentively. This complex process called "cross-shed welding" is far more technically demanding than the "soldering method". The types of materials that need to be selected for welding different wires, such as which wires should be thick, which ones need to be thin, which ones should use flat-head copper wires, and even silver wires need to be used in specific locations.

At this moment, Li Aiguo is already an expert and can handle it with ease.

He took out a thin copper strip from the toolbox, then picked up the electronic soldering iron, separated the cathode circuit next to the capacitor from the motherboard, and quickly used the copper strip to wrap the two together tightly. It only took a few seconds and the welding was completed flawlessly.

The welded wires look neat and tidy, and you can even see that the corners of some joints have been skillfully processed into almost straight angles.

Liu Aide stared at all of this for a long time, and seemed to find no signs of repair or modification.

"Liu Jianguo, your welding skills are indeed excellent, but you know that the trick to repairing radios is not just welding."

Suddenly, "click", Liu Aide's words had just fallen, and Li Aiguo took the opportunity to insert the power plug of the old radio that had been repaired into the power socket, and gently turned the power button. The sound of the radio starting normally appeared at that moment.

"Hiss...hiss..." As the clear, chaotic and irregular sounds gradually stabilized, the radio waves in the radio speaker began to become clearly audible.

At this moment, Wang Dali and Zhao Eryong were instantly energized. Once they heard the changes in the current and volume, it meant that their repair work had been mostly successful.

"Quickly adjust channels".

Zhao Eryong couldn't wait. He fiddled with the antenna with his fingers nimbly and turned the radio joystick to search for frequencies.

Soon, a few seconds after the adjustment, a clearly audible sound came from the radio speaker, "Beep-beep, hello, kids, the Children's Loudspeaker begins to broadcast stories."

The sound is amplified to two speakers through the sound amplification effect, as if the storyteller's voice is telling each story affectionately, and every word and every phrase can arouse resonant emotional fluctuations in their hearts.

Wang Dali happily stepped forward and patted Li Aiguo on the shoulder, "Great! It's really fixed. Now Brother Aiguo can make money happily!"

Just when he was excited and wanted to share the joy of earning 45 yuan this time, he suddenly caught a glimpse of Liu Haide standing beside him waiting. He quickly restrained his words, signaled with his eyes, and smiled at Liu Haide and went into the house to discuss more secretly.

Then Wang Dali pulled the door curtain, quietly took out a few cigarettes from his pocket, and handed them to Li Aiguo:

"Jianguo, this watch is sold for 15 yuan, plus the recycling price, the total is 55 yuan, so a round trip net profit of 50 yuan. This is much more profitable than collecting junk. We can close the junk shop and focus on collecting second-hand electrical appliances. After collecting them, we can resell them in the market or pigeon market. What do you think?"

"Huh? Doesn't that turn into robbery?" Wang Dali shook his head in confusion.

"We can't do that!" Liu Jianguo replied with a sullen face, and continued, "We haven't violated any laws or regulations, have we?"

Then Li Jianguo took a cigarette from his pipe bag, lit it and took a puff, "Let me tell you, are there still those small vendors who repair home appliances on the streets and provide services?" This question seemed to make Liu Aiguo feel a little uneasy.

Wang Dali was unable to speak but still refused to give up: "Then let's stop now." He seemed to be calculating the loss if he missed this opportunity. His heart was like a wild cat constantly gnawing at his will, making him feel unbearable.

"That's not necessarily true. Our scrap shop is directly connected to a scrap processing company. The cooperation contract we signed at the beginning clearly stipulates that the business of recycling second-hand materials and then re-listing them for sale after simple preparation is also a part of the business that is subject to legal supervision."

After finishing his words, Li Jianguo asked Wang Dali to take out the contract from the storage file box, and turned to the relevant clauses and pointed them to Wang Dali for confirmation. At this moment, there was a deep consideration of future planning and legal operation principles between the two.
