|The 22 watt amp is easy to build, and very inexpensive. The circuit can be used as a booster in a car audio system, an amp for satellite speakers in a surround sound or home theater system, or as an amp for computer speakers. The circuit is quite compact and uses only about 60 watts. The circuit is not mine, it came from Popular Electronics.|

|this is our project in our school. it's so nice and sounds good too. It is better when you put tone control on it with bass, treble, balance, and master volume...nice!!!!|
|how to attache bass, treble and volume controls with the circuit and also the audio cable?|
|Is there any substitution for TDA 1554 chip?? Its not available in my area.. :( plz suggest..|
|how can i connect a volume control in this circuit..????|
|Just to say to all: This is 22 watts PER CHANNEL|
|reply to: sameguy. Hi there. you need a preamplifier to use a mic. with the amp.|
|Thank you so much for the circuit diagram.I built the amp it work perfectly. I added LED (as power light), FAN (to cool the IC), DIODE on the positive power line which served as a protection in case polarity is mixed, 100k variable resistor for volume control and i also added Bass and Treble controller.For the power supply i use a PC power supply.All worked very well, so clear sound.I am very happy.Thank you .|
|This Amplifier is soo amazing and sounds soo clean..I Love it. The wires I used with the circuitboard were taken from an old telephone wire (excelent conducter). The Heatsink was held tight in place to the IC along with heat transfer paste. An old headphone jack with the wire was used for the left-in & right-in connection. Four 8 ohm speakers were used for the left-out & right-out connections(two for left & two for right) Only thing I need now is to make an attractive case for it and use it with my computer exclusively. My next project will be to build the "12VDC to 120VAC Inverter" which I will use with my Solar Panel Batteries...|
|Hi everyone. Instead of using a speaker as output, I want use headphone. Is this possible? I want to solder directly from this diagram of headphone jack http://techpubs.sgi.com/library/dynaweb_docs/hdwr/SGI_EndUser/books/Octane_OG/sgi_html/figures/speaker.headph.port.gif to the amplifier output. Please help me. I want to use my extra headphone. I still don't have money to buy speaker.|
|please i broke the signal ground. will it work?|
