In the fifties, ore radios were all the rage.

Tube radios are produced in limited quantities and are so expensive that even the average working family cannot afford them.

At the beginning of liberation, there were only more than 5,300 radios in the capital, and there were no more than 1 million in the whole country.

Next year, the largest electron tube factory in Asia at that time, the Beijing Electron Tube Factory (the predecessor of BOE) will start construction, and after it is put into production, the sixties will be the spring of domestic radio, and gradually enter thousands of households in the city.

Xu Deyong returned to the courtyard alley, and the time was less than twelve o'clock.

Xu Nanshi was holding things in his hands and chatting with the old ladies and women in the neighborhood at the entrance of the alley.

Seeing Xu Deyong coming back, a little surprise flashed in his eyes, so he stopped, and said to everyone with a smile: "My grandson is back, everyone see, my grandson is good-looking, and now he is making money by pedaling three rounds, and the day before yesterday he bought ten catties of noodles home, and cut a pound of meat yesterday, and said that he would pay five cents a day in the future, and let me save for my daughter-in-law." ”

"Then your grandson earns a lot a month!" Someone sighed.

"Not really!" Xu Nanshi said smugly: "In the past, the old man pedaled three wheels, which was more than enough to feed the three of us. Since his grandfather left, the child has also been sensible and willing to work, as long as there is this tricycle, the family does not have to worry about food and drink, and there is a surplus every day. If you have a suitable girl, don't forget to introduce me to my grandson. ”

Xu Deyong was a little speechless, co-authoring grandma This is Zhang Luo to let others introduce him to him, and he also sold melons and boasted about himself.

Everyone looked at Xu Deyong, they all knew or heard that Xu Deyong was a good person, and he became better for a while, but he couldn't explain anything.

Even if you give an introduction, you have to observe for a period of time, Xu Deyong has no father or mother, he doesn't even have a brother or sister, and he doesn't take care of him, which is also a shortcoming!

Besides, now that there is a formal job, it is not easy for Xu Deyong to find a good appearance in the city.

At this time, Xu Nanshi saw the things in Xu Deyong's tricycle.

After looking at it carefully, he was surprised: "The grandfather clock can move!" Deyong, has it been fixed? How much money was spent? ”

Everyone also gathered around to take a look, after all, clocks and watches are big objects, and many families don't have dozens or hundreds of new ones.

"Hey, that's moving!"

"What time is it?"

……

The crowd was gossiping.

"It's eleven fifty." Someone knows the Tao.

Xu Deyong glanced at the old lady's inquiring gaze.

Yes, the right should be given to the old lady with a long face!

He said with a 'delight' on his face: "This clock is not a big problem, I spent two cents and a half to buy some watch oil and parts, and borrowed other people's tools to repair it myself." ”

Xu Nan's voice raised and he said in surprise: "You cultivated it yourself?" It's true? ”

Xu Deyong raised his head and said: "Of course, I also helped someone else repair one, and they gave me the tool to offset the maintenance fee." ”

He wants to say that he bought it for five dollars, and the old lady will die of distress!

Xu Nanshi picked up the small sack and looked at it, only to see that there were many tools.

"Gee, these tools cost a couple of bucks." An aunt glanced at it.

Xu Nanshi believed it a little, because Xu Deyong didn't have so much money to buy it.

"Oh, my grandson can fix clocks, you say I don't know, I learn some mess outside all day." Xu Nanshi sighed, but his face was full of energy.

"If you have the ability, you can repair tricycles and clocks." Aunt Yi's eyes moved, and she said with a smile.

"Really?" Some people don't quite believe it.

An aunt said: "Yesterday morning, I had to repair three rounds, and many people in our hospital saw it, and I knew it as soon as I inquired." ”

"It turns out that Yong is deeply hidden, and he will have so many skills at a young age, which is amazing."

"Deyong repaired a bell for people, and he got something worth several yuan, and if he had this skill, he would make more money if he set up a stall and opened a store."

……

Everyone praised it, and there were a few families who had problems with their clocks and watches, and they were reluctant to spend too much money to repair them.

If you don't go back and ask Xu Deyong to repair it, you can't move it anyway, and the neighbors can still charge more?

In the compliments of everyone, Xu Nan's face smiled, and his grandson gave himself a long face.

Xu Deyong stood aside, being a beautiful man, ready to continue.

Sure enough, Xu Nanshi found the red box again, and said curiously: "What is this?" ”

Xu Deyong said: "Ore radio." ”

"Radio!" Xu Nan's voice raised again, how the things that this grandson brought were more surprising than the same.

Attention shifted again, after all, the radio was much more influential than clocks.

"Oh, this is the drama box, I see who has listened to it with headphones at home, and someone is singing in it, it's amazing." An old lady said.

"And I've heard that there is no electricity yet."

……

Good guys, there is gossip in the ears, and everyone is enthusiastic.

Xu Nanshi asked, "Can this listen to people singing?" ”

Xu Deyong nodded and said, "Yes, but this is a bad one, and it is also a gift from the clock repairer." ”

"It's bad." Disappointment flashed across Xu Nan's face.

"This is also sent, what a loser, I can't listen to it and it looks good in the living room!" There is humanity.

"Deyong, this is when you meet a rich family, there must be that kind of radio that can directly emit sound at home, hundreds of it, this kind of bad old nature doesn't care." There is a way to understand.

……

After everyone finished speaking, Xu Deyong continued: "However, change the earphones, replace the bad parts inside, and make an antenna that should still be able to listen." ”

"Can it be repaired?" Xu Nan's eyes lit up, and then he said: "Then it costs a lot of money to buy any headphones." ”

Xu Deyong said: "Two or three pieces are about the same." ”

As soon as he heard that the flowers were two or three yuan, Xu Nanshi was suddenly reluctant.

An old lady next to her said, "Two or three yuan is not a small amount. ”

Another woman said, "If two or three dollars can listen to the drama box, I am willing to spend it." ”

Yes, after all, this is a drama box that can listen to the play.

"Grandma Deyong, if Deyong repairs it back, let me listen to it, I haven't heard it yet." An old lady said.

Others also agreed, and praised Xu Deyong in their mouths, anyway, good words don't cost money.

Originally, Xu Nanshi didn't want to spend this money, but when he heard everyone gossiping, he gritted his teeth and said, "Deyong, are you sure you can fix it?" ”

Xu Deyong nodded and said, "Eight or nine is not far from ten." ”

Ore radio only, simple structure, ore detector, coil, capacitor, splitter, binding post, headset and other parts.

If the parts inside are broken, just buy the parts and replace them.

"Okay." Xu Nanshi made up his mind and said: "Go home, grandma will give you three yuan, and you go buy things to fix the drama box." ”

Everyone heard that Xu Nan was willing to take money to repair, and they were more enthusiastic, who didn't want to hear a novelty.

Jia Zhang was also in the crowd, and he kept a cold face and didn't speak, obviously a little unhappy to see Xu Nan and Xu Deyong's mother in the limelight.

After all, she and Xu Nanshi often quarrel in the courtyard.

"If this theater box is repaired, counting the clock and the tricycle, you will have three big items in your house." Careful people have the math.

Everyone thought about it, but it wasn't.

Don't talk about Xu Deyong, when you talk about kissing, if you say that you have these three things at home, you will definitely be looked down upon.

At this time, marriage is not yet popular, "three turns and one sound", after all, most families do not have it, and there is no climbing.

Weddings are simply called the "Four One Project": a double bed, a thermos, an enamel basin and a spittoon.

If there are "twenty-four legs", it is a good person, a large cabinet (four legs), a high and low cabinet (four legs), a dresser (four legs), a dining table (four legs), and two chairs (eight legs).

Looking at the grandmother who was surrounded in the middle, Xu Deyong silently retired, meritorious and famous!

The smile on Xu Nan's face couldn't be put away, this was her happiest day in more than ten years.

"I have to go home and cook for my grandson, and after eating, my grandson has to make money, see you back."

Xu Nanshi smiled and got rid of everyone and followed his grandson home.

Xu Deyong parked the tricycle, holding the box and clock, and carrying a small sack of tools in his hand.

Xu Nanshi smiled and complained: "You just do lazy work, and if you can't come back and get it, what if you fall along the way." ”

Xu Deyong said: "Your grandson has a lot of strength, this thing is drizzling." ”

Back at home, Xu Deyong put the clock back on the cabinet, and the sound of the bell was very pleasant.

Xu Nanshi looked at it with a smile and said, "Go a little further to the left and put it right, otherwise it won't look good." ”

After Xu Deyong set it up, it was exactly twelve o'clock.

"Bell, bell, bell......."

The melodious bell rang, and finally another voice rang in the two small rooms.

Xu Nanshi listened attentively, and his body remained motionless, as if he was afraid that the bell would not ring if he moved.

Until the twelve rings are over!

Xu Deyong turned his head to look and found that his grandmother was already in tears.

He hurriedly went over and put his arm around the old lady's shoulders and said, "Grandma, what's wrong with you?" What are you crying about? ”

Xu Nanshi choked and wiped his tears and said, "I think of that dead old man, how happy he would be if he didn't die...... Well......! ”

Xu Deyong was also a little emotional, and gently patted the old lady on her back and said, "Grandpa will definitely be able to hear it in the spirit of heaven, and listen to it every day in the future!" ”

Xu Nan's emotions came and went quickly, and he seemed to be a little embarrassed, wiped away his tears and said, "I'll cook for you." ”

Seeing that the old lady was busy and had a smile on her face again, Xu Deyong shrugged, put the ore radio on the table and began to tinker.

This is an AAMI brand ore radio produced in Shanghai, and it is impossible to see when it was produced.

The lid of the box is opened to reveal a simple rotary button and an ore geophone, two headphones on each side and a binding post for the bottom line.

In short, the structure is simple!

With the spread of radio knowledge and the development of industry, in the sixties, many teenagers from well-to-do families would think that they would make ore radios as very interesting.

These teenagers in their own courtyard obviously don't belong to this category, and they don't have much pocket money!

Remove the wood panel containing the parts, and the damage to the circuit can be seen at a glance, and the quality of the parts must be carefully observed and judged, otherwise you will have to spend money in vain.

Fortunately, his eyesight has also improved, and he definitely reached 5.0 above.

He muttered as he inspected it: "The ore geophone should be broken, the coil is also aging, and the variable capacitor is ...... It seems that ...... can still be used. ”

Xu Nanshi glanced at Xu Deyong from time to time, and she was curious about how her grandson cultivated.

However, after watching it for a while, I felt that I was not interested in retracting my gaze, as long as I could listen to the sound tube how he repaired.

But the thought of spending three dollars made her heart ache.

This money has just arrived, and it hasn't been hot yet!
