Transistor 2N3055 Circuit with 1.5 Million High Gain
Transistor 2N3055 Circuit with 1.5 Million High Gain is like normal volume knob it can make sound more but not too much and if we want very loud like 1.5 million we need to trick it little bit. One way uses two transistors together like a double volume knob. People also call this arrangement a […]
Simple LM317 Audio Amplifier Circuit
This Simple LM317 Audio Amplifier Circuit is a kind of like small trick to make speaker sound louder; also this LM317 chip usually is used to control voltage but here it works like small music booster amp. Therefore, it is not very strong amp but still helps give little more sound from the music source; […]
Public Address Amplifier Circuit
This Public Address Amplifier Circuit works like a very strong loudspeaker for our voice! When we speak on microphone then it makes our voice go very loud because of that many people can hear us good. Hence, this circuit is good for big place like school, office, stadium or parties where we want all people […]
Simple FET Preamplifier Circuit
To begin with, this Simple FET Preamplifier Circuit works like super booster for small sound, as it uses special transistor, FET to make quiet sound go more loud. Also, this circuit is very good, because it uses two kind of transistors N channel FET and PNP bipolar, together they make sound strong and not bad. […]
Simple IC TDA2822 Stereo Audio Amplifier Circuit
Simple IC TDA2822 Stereo Audio Amplifier Circuit is small chip with stereo amplifier makes weak music sound go louder which is strong enough for speaker or headphone. However, despite using very little energy it still provides 250 milliwatts each side with good sound for small things like walkman, hearing aid or little stereo. So next […]
