Multipose 1Watt Guitar and MP3 Amp

[M23Bomber]

Hello All,

Feel free to build the Multipose 1Watt Guitar and MP3 Amp.

Features:

- Guitar Amp kinda like the Punch Amp,

- Joint Stereo Plug for MP3 player,

- Runs off a 9v battery

If anyone wants to perfboard, stripboard or turn it to a PCB please make it public also in this thread.

Regards,
M.

nice idea, sounds like it could be really handy in a travel situation. how does the TL071 sound with MP3s? just asking because i once planned to build a headphone amp, but was told that the TL07* series wouldn't sound too good with full-spectrum audio. a Burr Brown opamp was recommended to me. if it sounds good already though, doesn't matter!

Actually the TL071 does the job. At the volume I use it i wouldnt be very noticed. Also the TDA7052 does deal very well with output loads higher than 8 - 16 ohm, that makes it a bad headphone amp.


My goal is to have a all in one amplifier that would allow me to share music outdoors and also some one wants to jam along with a guitar. But this is a first draft.

? ? ?

Much commercial music has already been through multiple (even dozens) of TL07x opamps.

I would argue that listening to any MP3 is a bigger sin against music than all the TL07x ever made.

Actually the IC in  my Project was the Vintage Polish  ULY7741. But the t
TL071 does a good job as well.

Im going ti Update the schematic soon because the TDA7052 simply BURNS up when a speaker impedance higher than 16ohm is plugged such as some headphones. Does anyone have trick that would allow it run with any Load?
