Today I have collected a small amplifier IC circuit to you. Most of the old series. and It is a simple circuit OTL series, mini size capacitor chupling to small speakers. -Although the number of IC may not be stock. It’s very hard to find now. But may have come …
Currently, ICs has been used in many audio amplifiers,especially small circuit. It is convenient to use transistors.But when you need to use transistors, it has several advantages, such as saving you can take old equipment come to made small circuits easier than the IC. Which may be difficult to find. …
