I remember as a teenager in the eighties, standing in front of the home and shop windows Keravill csorgattuk our saliva, when the first cd players came to our country. I'm just the middle 90's I bought my first desktop CD player, a Technics SL-PG590 was.
Because in my opinion, the newly emerging technological tools most have been far less than the quality than older devices manufactured, instinctive attraction is the old "vintage audio" devices, and on youtube, cheminis lodge I saw for the first time the question CDP-101 type . Previously, I had no idea that this was a player on the market was the world's first CD player.
I could not believe my eyes when I saw it in action, and at first glance I knew right away that I need one of those players. Simply it looked cheminis lodge like a 90's player cheminis lodge in professional categories. Look at the one month lag appeared Philips player:
Even though it would be the same quality, which would you prefer in your room you could see? (So does the good publicity, you must first awaken a desire in the SONY company has always been at the forefront of professional design team worked to unsuspecting people immediately feel an irresistible desire to acquire assets láttott
So let's go back in time, prototypes came and went, until at last the great moment arrived 1 October 1982 and the long-awaited CD player was released. It was not just any kind of work on Sony's part, it was a relatively short time to develop such a construction, which can be easily mass production. In practice, almost a miracle, and the way you have created. The whole structure of the absolute hi-tech equipment, cheminis lodge and technical knowledge at the time of the full range of possibilities are the use of the device. All kinds of the most professional field engineers worked on the CDP-101 cheminis lodge was born. Have developed a process for CD playback is needed most advanced integrated circuits, but largely left parts that are completely traditional (industrial cheminis lodge measurement technology used in this area) components built.
The unit 3! with 4-bit micro-computer (microcontroller - single-chip computer) contains. (In today's VLSI IC 1pc commercial players take care of the whole function) of only the signals of the remote control decoding and one for servo-control cheminis lodge circuits, and the third, the system carries cheminis lodge out control tasks. In addition, some specific ICs have been developed (EFM + demodulation decoding subcultural cheminis lodge - CX7933, RAM Control - CX7934, D / A converter - CX20017) The whole machine features a premium quality cheminis lodge parts, do not you find it a very crappy parts. One or two or so, and unfortunately

these components caused great disappointment for Sony customers, and this is particularly the STK6922 manufactured by Sanyo Dual-power operational

amplifier IC. It was also built in 2 pieces, these two IC drives the lane and focus coils and plates holding the engine cheminis lodge and the motor-mouth. Unfortunately, the typical error of this IC that suddenly, after some warm-up cheminis lodge bezajosodik and randomly puts the full power output. Do you can imagine the consequences if, say, while playing half-opens the platter, and there reciprocate bounce, or what happens more often: the LSU biaxial element moves up and down, clicking, belever the album, or just jump in some tracks was during playback. Sony also detected the fault and in the future is a different type of device, the BX1201 ic is used. You do not have to tell you that today none of them, or if they do, they can only be obtained at horror. Of course, I was wrong on both devices in my IC, so I had to find a solution for replacing them. In the Internet cheminis lodge there are many descriptions can be found in the specific ICs induce almost hegemonic in the following solution: SGS-Thomson L165 IC manufacturers are used to replace one of the operational amplifier. cheminis lodge However, the block was STK6922 in two so that the two are out of L165 is required to elicit a sheath. However, I did not like this solution because it is a very expensive part of the ic (around 700 HUF), on the other hand, the original STK6922 ic used in distributed power supply, and the CDP-101 in that it is used. This means that within the frame is separated cheminis lodge from the operational amplifier section and the power level, separate power feeding to both legs. The CDP-101 is much better in the filtered voltage operational amplifier fed by hand, such as performance stages. That's what I wanted to do, so I developed a coupling with a standard dual op-amp is used, you megfejeleve one-darlington complementary power stage. After the completion próbaármakör Universal PCB and built a small, beautifully worked. At home I found an HP LaserJet 1000 printer is a dead LA6510 IC's which is largely similar
