TDA2040 Instrument Amplifier

Posted on March 27, 2012March 27, 2012 by abram

the need for small and portable amplifiers has arisen mainly by a desire to come up with some sort of all-purpose busking amplifier. here is the first screen shot of the output from the preamp section. the entire amplifier is powering an Eminence Beta-12LTA off of a mere 6V. don’t ask me how. it took a while to find the right combination of resistors for the TL082 to run stable at such a low voltage. it’s also surprisingly loud being that it’s about 26V away from the recommended supply (±16V). i’ll probably be posting a schematic soon.
