The simple amplifier

This is a simple amplifier to build and will take less than 20 minutes. The best part is that you can buy all the parts at radioshack.

Sorry about the crappy video quality. I got it from my old metacafa account.

ok i made this and tried it out on 10 w and 0,5 w speaker........ on 10w speaker it was realy quiet, on 0,5w speaker i didnt hear anything where is the problem bro?

[cordcole]

@padly88 to clarify it is a 1 watt amp and it depends on how many the volts are and how much the input power is. hope that helped

[AJpennster]

@cordcole if u take a capacitor and add it to pins 1 and 8 you can increase the power to 200 rather than using 20.

[cordcole]

@AJpennster ok thanks, ya that will do it

[padly88]

how much did it all cost?

[cordcole]

@padly88 10 bucks or less

@padly88 you may need an high impedence speaker such as 32 ohms or maby eaven higher
