High quality sound amplification technology - DataSet
This Group aims to improve the sound characteristics of the output signal from the audio viewpoint when the silicon transistor is used in the acoustic amplifier circuit in the acoustical equipment field.When using a silicon transistor in an acoustic amplifier circuit, the sound output is known to be cool, rough, sharp, and not abundant. So audio enthusiasts still like amplifiers that use vacuum tubes. Audio enthusiasts have an excellent ability to judge sound quality because of their ability to listen to sound.So this Group shows how to remove the insufficient sound characteristics of the silicon transistor and improve it with the sound of the tube.We will discuss the process of making this part by applying this improvement method, and finally make it a real part.
The original written in Korean has been included.
Please use only the largest revision number among several files. The rest is data for comparison.
Among the published materials, there is a way to deal with errors when generating BOM files from the PCB design file (Kicad). After downloading the Kicad data file, the Kicad data file name and directory name must not contain spaces. Please change the space of downloaded data file name to "-" or "_".
Notes on prototype products.
The prototypes posted in this group are intended to be used for review to proceed with the project. It is inappropriate to use it for real life purposes.
Prototypes posted in this group are not fully operational and safety tested. I have made the product and made the data by judging within my knowledge range. I am not responsible for any damage or damage caused by this prototype product.
