“This is small power (about 14~18Watt) audio amplifier utilizing TDA2030 chip IC which is now obsolete.
The TDA2030 was manufactured by STMicroelectronics that is joint electronic company between France and Italia.
But analog audio device production had been stopped and this audio chip is no longer available.
Meanwhile somehow I still have four TDA2030 ICs (maybe I bought these chips about 10 years ago and simply forgot to use) in my parts inventory.
Although you cant buy TDA2030 any more, a general audio amplifier making method explain in this instructable can be still helpful to make other amplifier which using still available audio IC chip such as LM1875.
Ill introduce other audio amplifier DIY project using LM1875 in another instructable later.
Lets start story about making small power amplifier which can be used as PC speaker.”
