 It took a while before the radio returned to normal and played the music from the tape.
 "Sweet honey, you smile very sweetly, like flowers blooming in the spring breeze..."
 An unknown singer has a pretty nice voice.
 "That's the problem. It was like this when it was started at the beginning, but it got better later on, and I don't know why..."
 As the little uncle spoke, he suddenly felt uneasy.
 He has found several merchants, wanting to repair this thing.
 But these merchants dare not accept work at all, because once it is repaired, they will lose money.
 These ancient electronic products are very delicate, and a certain line inside may be broken after a few touches.
 What's more, the production of various parts of the radio has long been discontinued.
 Even if there is a factory to produce it, it cannot be sold at any price. Antiques and antiques all want the word "ancient". If modern electronic components are installed on ancient instruments, what is the difference from pasting a piece of dog skin plaster?
 Anyway, it can still be played normally, so the little uncle can only make do with it.
 Zhang Yuan eagerly walked to the radio: "Let me fix it!"
 "Then... well."
 "You try it."
 Clearly a tone of distrust.
 The little uncle complained endlessly in his heart, feeling that he was too embarrassing.
 Although my nephew is awesome, he is a "spaceship management" major, and can even repair spaceships, but there is a huge difference between repairing spaceships and repairing radios!
 The most important thing is that it is impossible for my nephew to lose money if it is repaired!
 Seeing that Zhang Yuan's hands had already touched the radio, his heart twitched fiercely!
 But because of his face, he couldn't say anything more, he just looked back at his daughter viciously.
 Ye Qingqing did not show any weakness, and stared back at her father with a smile in her heart. In her opinion, the production of this kind of antique has long been discontinued, and even the design drawings have long been lost. Who else can repair it?
 Especially... the difficulty of dealing with small problems is actually far greater than that of big problems.
 After overthrowing my cousin, a "child from someone else's family", I can finally breathe a sigh of relief, and it seems to prove that "studying is useless", and I can read less books in the future...
 At this time, Zhang Yuan had already unscrewed the casing screws of the radio, exposing the electronic structure inside: switches, power supplies, variable capacitors, potentiometers, magnetic rods and other structures, which were not too complicated.
 It is these uncomplicated things that have withstood the test of time and survived until now.
 The more complex and exquisite things are, the more likely they are to be damaged. In the 21st century, there are very few Warwick and Apple smartphones left, and each of them can command sky-high prices.
 Zhang Yuan has never repaired this kind of antique, this is a brand new challenge.
 In the past, he might have avoided it, but now, he has a wonderful desire to explore in his heart.
 Taking a deep breath, the brain began to work rapidly.
 He tried to deduce how the radio worked from what he had learned in the past.
 Any electronic device plays with electrons and magnetic fields, which are essentially the same. The working principle of the radio is nothing more than converting the audio signal through various circuit structures.
 "And this radio just used tape broadcasting, so the antenna, variable capacitor, and detection circuit are basically useless. The noise that came out at the beginning is unlikely to be due to errors in these parts..."
 "Could it be a tape problem?"
 Zhang Yuan took out the tape, reset it manually, and put it back in again.
 "Sweet honey, you smile very sweetly..."
 This time, the playback starts from the beginning, with no noise in between.
 Zhang Yuan changed another tape and pressed the play button.
 "I can't stop loving you..."
 Still no noise.
 "So, it shouldn't be because of the tape."
 The little uncle looked at him trying again and again, and became more and more anxious. He said quickly: "Only when starting up, there will be noisy noises, and then there will be no more. It really can't... just forget it..."
 One of his hearts was always tugging, and he just hoped that his nephew would be able to retreat in spite of the difficulties.
 Don't fix it.
 Sir, don't break it!
 "Is it only at the beginning?" Zhang Yuan waited for a while, and then took the radio under the air conditioner and played it for ten minutes.
 Plugged it back in, and sure enough, the cooled radio started yelling again.
 "Buzz-buzz!"
 The piercing voice made my liver hurt.
 It took a while before it stopped.
 Zhang Yuan was thoughtful.
 The whole process of troubleshooting errors is somewhat similar to debugging in computer programming. Now that you have identified how the bug occurred, you just need to find the cause and fix it.
 Zhang Yuan paced back and forth in the room, quickly thinking about the suspicious points.
 Poor contact?
 No, bad contact doesn't yell at first, it just stops working intermittently.
 "It's not a phenomenon of current mics either."
 After much deliberation, it is likely to be a warm-up problem.
 This old radio uses vacuum tube technology.
 There are two main devices in this near-vacuum sealed chamber: one is called the heating electrode, which is located in the center of the tube and emits light when it is working; the other is composed of the cathode, metal grid and metal plate.
 "If the vacuum tube warms up irregularly in the circuit, the voltage of the entire circuit will be disturbed. This part of the disordered voltage is mistakenly transmitted to the subsequent amplifier circuit, so when there is no electrical signal, the tape recorder screams."
 "And finally, when the radio frequency lines were fully heated up and the tube voltage was adjusted, everything went back to normal and the tape recorder worked."
 As soon as Zhang Yuan clapped his hands, that should be the reason!
 The little uncle saw Zhang Yuan pacing back and forth, just eating fruit, and he felt that he was in a bad mood: how could a normal repairman walk around at the same time.
 Ye Qingqing just pursed her lips and snickered.
 Zhang Yuan lowered his head, squinted his eyes, and began to disassemble the vacuum tubes one by one.
 He really started tearing it apart!
 I……
 The little uncle was about to cry without tears, and trembled all over: "Zhang Yuan, it's really impossible, let's go to a professional antique repair shop! I know a very good master...but the price is a bit high."
 Zhang Yuan turned a deaf ear and devoted himself wholeheartedly to his work. He really didn't hear what the little uncle was saying.
 He rearranged the order of the vacuum tubes, screwed on the screws, and waited for the radio to cool.
 The little uncle's face was flushed, and he couldn't help muttering in his heart: It won't be broken, right? Is there an extra part?
 Even my sister-in-law couldn't stand it any longer: "I see you're nervous, it's just a radio, what are you doing?"
 "What do you know? Even if it's just a radio, do you know the history of it, it's..."
 Zhang Yuan didn't answer, but just pressed the play button.
 Click——
 The radio is like a docile sheep, warming up obediently, and there is no more noise.
 "Sweet honey, you smile very sweetly..."
 The soft singing echoed in the air.

 Cen Qing transmigrated into a book, transmigrating into the villain who single-handedly created the zombie virus in the post-apocalyptic novel. 
 It’s not scary to dress up as a villain, what’s scary is that there is a villain who is more powerful than her. 
 Looking at Jiang Ci who was still dormant in the culture medium in front of him, Cen Qing recalled his own ending in the original book, his little heart trembled. 
 Did she kill him before he turned black and grew up, or pulled out his oxygen catheter now? 
 But Jiang Ci’s first sentence after waking up was, “Mom.” 
 Cen Qing was so frightened that the hand that pulled out the oxygen tube swished back, and since then began the daily routine of raising a baby/raising a man in the last days. 
 “Qingqing, blood is drawn on the hand, it needs to be healed to be healed.” 
 Cen Qing glanced at the wound where a drop of blood appeared, and ignored him. 
 “Qingqing, the zombies are Ah Ci’s good friends, can you stop beating their heads?” 
 Cen Qing glanced at the zombie with its bloody mouth open, and slammed the stick again. 
 “Qingqing, he pushed me on purpose. I don’t care at all that you stay in the same space as him.” 
 Cen Qing glanced at his stunned assistant and sighed. 
 Who did Jiang Ci learn the tea-in-tea phrase from? 
 But the day-to-day life of raising a baby suddenly changed his style of painting one day. The reason was that Cen Qing recruited another male assistant, the kind who looked soft and cute. 
 The man pushed her against the wall, his dark eyes filled with strong possessiveness, his voice was hoarse, 
 “Qingqing, you are not good, and a disobedient child should be locked up with chains.” 
 Cen Qing, who was trapped in the man’s hot embrace and could not move, burst into tears. 
 Is it too late for her to pull out the oxygen tube now? Waiting online, very urgent.

Now that the blue star is soaring, the alien beasts are raging, the aliens are invading, and the people of my blue star are in danger. ‘Secrets’, ten dollars will be given to you, and the task of maintaining world peace will be entrusted to you in the future.”

 The liar was content with the money and left with a fake cheat book.
 And Xu Lingjun returned home with the secret book, stretched out his hand and patted it. The shabby book immediately radiated a glorious, desolate and ancient atmosphere, overwhelming the stars, and arbitrarily forever.
 Fake?
 Just kidding, in front of me, the actual product does not match the introduction. Please refer to the actual product as the standard. This sentence does not work.
 PS: I have finished the old books “The Counterattack of the Infinite Supporting Actor”, “The Master of Infinite Qi Luck”, “Taobao Merchant of Ten Thousand Worlds”, and “Genuine Cultivation”, all of which are excellent! The fine book “From Reiki Recovery to the Age of Domination” is being serialized. The old author has a good character and is trustworthy
