|This is a handy, easy to build general purpose 50 watt amp. The amp has an input for a radio, TV, stereo or other line level device. It also has a phono input for a record player, guitar, microphone or other un-amplified source. With the addition of a low pass filter at the input, it makes a great amp for a small subwoofer.|

|Can someone please tell me where to connect all the earth GNDs...|
|ICL8063(U3),which other IC can I use to replace it for better result.Kindly reply through my e-mail.Thanks.from Nigeria|
|what value low pass filter do you recommend for use as with a bass guiter? Should I build it separate, or utilize a second input with the filter? That way I can use the amp for other things if needed.|
|I'd use replacements where the 741 opamps are. They have crappy frequency response, crappy noise ratings, and crappy slew rate.|
|p=v^2/r p power in watts v rms voltage, volts r load resistance|
|U3 also known as ECG8063|
|does anybody can tell me about the computations of output power of an amplifier?just reply on my e-mail.|
|where ic can i use for U3|
