"Ahh Duan Yun's mood suddenly became excited when he heard this.

For Duan Yun, it is of great significance to be able to obtain a channel to purchase chips, which means that Duan Yun can start to design more complex and advanced circuits!

Although there are only some chip products in the sixties and seventies of international developed countries, their performance is still very advanced in China in today's era, and even in later generations, chips such as NE555 are still produced and sold in large quantities, which have a very important value in the production and research and development of electronic products.

For Duan Yun, these chips have very important value to Duan Yun, one is to modify the gear hobbing machine, using these 6502 microprocessor chips, Duan Yun can transform the milling machine into a powerful gear hobbing machine, and the other is that the preamplifier that can be used to make audio and video, voltage comparators, and other electronic systems is also a very common part of daily electronic products in later generations, if Duan Yun can buy this kind of chip, the audio equipment made will be much more powerful than the current effect.

In addition, more importantly, there are not many high-end talents who understand chip technology in China, most of them are concentrated in the country's key military enterprises and scientific research units, and there are very few people who can play with this chip in ordinary electronic technology enthusiasts, in addition to the international blockade of this chip in China, domestic chips due to poor production technology, the product qualification rate is too low, resulting in high prices, destined to not be popularized, so it is very difficult to plagiarize technology and mass production of speakers equipped with this chip in China, so it greatly avoids the possibility of vicious competition caused by pirated imitation of Duan Yun subwoofer！

However, when he saw this list, Duan Yun's brows couldn't help but furrow slightly.

It turns out that the price of the integrated chip on the list is very expensive, a NE555 chip costs 20 yuan, in the memory of Duan Yun's previous life, the price of this low-end chip in the 80s in the international market is about one dollar, according to the 82 years of RMB to the US dollar 2:1 foreign exchange rate, about 2 yuan, and the other party actually opened a price code of 20 yuan, which is ten times higher than the international price!

In addition, the price of the 741 op amp is 35 yuan, and the price of the 6502 microprocessor chip is as high as 60 yuan!

But considering the price profit of Duan Yun's subwoofer speaker, as well as the great value of the modified gear hobbing machine, this price is still acceptable to Duan Yun.

"This ...... Are you sure the other party really has the goods?" After a moment, Duan Yun asked with a slight frown.

"The shopkeeper does have a way in Hong Kong, I see he took out some electronic parts or something to show me, not enough I don't know if it's what you want, and I also bought this brand-name suit from him. Gao Lei said.

"He's a seller of electronic watches and a suit?" Duan Yun asked with a smile when he heard this.

"That old guy sells everything! Although his shop is inconspicuous on that street, there are really a lot of people who come to him to buy things...... Gao Lei said.

"Hmm. Duan Yun nodded when he heard this.

From what Gao Lei said just now, Duan Yun can basically determine that the other party should be specially collecting foreign garbage from Hong Kong, sorting the collected things and selling them through other channels.

"I feel that the price he gave is too expensive, a small electronic part costs dozens of yuan, it's just a money grab!" Gao Lei said with some resentment.

"Hehe, but people have an exclusive source of goods, do a monopoly business, and have the right to speak on pricing. Duan Yun said after putting the list away.

"What is a monopoly?"

"It's that he has goods that others don't have, so they can only buy his things. Duan Yun pursed his lips, and then said: "It's really hard for you this time, I'll make a list of purchases when I go back, and the next time you go to Guangzhou, I'll bring you money, and you can help me bring some goods." ”

"Okay, it's all trivial, anyway, it's easy to carry electronic parts on your body. Gao Lei said.

"And this one for you. As Duan Yun spoke, he took out a key from his pocket and put it in front of Gao Lei.

"It's ......"

"The motorcycle with a five-pointed star on the sidecar in front of my rental house is yours, and you can go over and ride away when you're done eating. Duan Yun said with a smile.

Some time ago, Yun bought another nephew, which was specially reserved for Gao Lei.

Duan Yun doesn't have the habit of letting people work in vain, in fact, no matter whether Gao Lei finds those chips in Guangzhou this time, he has to give Gao Lei a nephew.

Mainly considering that it is not easy for Gao Lei to do a small business, it is very hard to ride a bicycle to buy things in other factories, and the bicycle can't bring much goods.

In addition, Duan Yun can't do without the factory now, and Gao Lei can help him run errands in the south or other places, which is very useful to Duan Yun, and the two have begun to establish a relationship of trust, so it is still necessary for Duan Yun to win him over.

"Great!" After getting the motorcycle key, Gao Lei looked excited.

"But to be clear, this car is very fuel-intensive, and if you can't refuel in the future, don't say I didn't remind you. Duan Yun raised his eyebrows and said.

"Hahaha, what's the matter, isn't it just a little gas money, trivial. Gao Lei smiled when he heard this, then picked up the wine cup and said to Duan Yun: "Come, let's go with each other!"

The next moment, the wine glasses of the two of them touched crisply......

......

In the evening, after dinner, Yu Shulan washed the dishes in the kitchen sink.

"Xiaolan, I'll wash the dishes, Mom asked you to go to the big house, he has something to say to you. At this time, Yu Shulan's second brother came over and said.

"Uh. Hearing this, Yu Shulan shook off the water in her hand, and after answering listlessly, she came to the big house.

"Xiaolan come here, sit here with my mother. Yu Shulan's mother greeted her daughter.

When Yu Shulan heard this, she sat on the edge of the bed expressionlessly.

"Hey......" Seeing her daughter's depressed look, her mother said with a concerned face: "Mom knows that you are uncomfortable......

"Mom, don't say it, I'll listen to you. Yu Shulan bit her lip and said.

"You said you were obedient, but what you did yesterday...... Is that called personnel?" The mother frowned, and said to Shulan: "How good is the person your eldest sister introduced to you this time, like your brother-in-law, she is a clerk of the 616 factory, graduated from a secondary school, and her family background is good, and that kid is honest at first glance......"

"Honestly, that's obviously a nest......" Yu Shulan said softly.

"But how good the young man is to you, every time you come to our house, your hands are not empty, either to buy wine for your father or to buy fruit for me......"

"I didn't eat what he bought. Yu Shulan pouted slightly.

"Even if you don't eat, you can't beat him?" the mother sighed, and then said: "A very handsome young man, the left side of the face was swollen by your slap, if it weren't for your sister who saw me riding from 616 at work this morning, I wouldn't have known that you actually had such a heavy hand!"

"He deserves it! Who made him want to play hooligan on me? I warned him a long time ago!" Yu Shulan said with a look of gloom on her face.
