  • TDA2040 PCB layout…

    backlit PCB layout of the TDA2040 solid-state amp i’ve been working on. i’m still using perf boards until i wrap my head around designing PCB layouts in EagleCAD. i do a lot of work in the dark.

  • TDA2040-based amp schematic with EQ…

    well here’s the first draft of the simplest medium powered solid state design i could muster. TL082 can easily be substituted with a TL072 which is probably better anyhow (i just have all these TL082s laying around). the power supply i’m using more like 14-15V. both ICs should easily be able to handle up to…

  • TDA2040 amp prototype…

    prototype of a 20-watt TDA2040 based amplifier that i’ve been working on. running a 12-volt power supply and it’s surprisingly loud.

  • TDA2040 Instrument Amplifier

    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…
