As C13 is used to stabilize the amplifier I would just like confirmation that the parts list and silkscreen are correct.

Please double check the information below, as I do not have alot of knowledge about electronics yet I am a newbie. Anyone has any idea on how to be qualified in order to build this amplifier without major mistakes?

This will give good protection to the actual amp circuit but will not blow for shorted bridges or lytics! Thank you for this really great article.

Thank you for sharing this documented design guide for LM Second is there any need for preamp as my audio source would be a laptop or a smatphone. Circuit Basics on April 1, at 2: Im considering building the amp, but i have a question that i sadly havent found an asnwer to.

Any idea what it can be? I have a question though. George on December 10, at Should I still include a ground loop protection circuit or is it not needed for this approach? I decided on a gain of around 27 db Robert Thank you very much for the reply.

You explain in the tutorial and as the actual photo of the cap datasheett the actual value of the polypropylene is. Howeveris it possible to go directly to EDA with info you posted for the amplifier board?

Datashwet board layout has allowed for flexibility which will allow for experimenting with components. Mono blocks, rather than stereo, the volume control before the amps, not in the amps, using a passive or a buffered pre-amp is essential for quality The power supply is all important and IS a part of the signal path, it controls it. Package is still on ship.

Click on the image to edit the schematic or change component values. George on October 19, at 8: However If amp is run at near full load not likely heating effects dataseet the transformer and bulk storage caps should be cooled as well.

Fusing both AC line input and power rails are the best but more work and expense. Thank you in advance!

But the question is if the motors operation would generate enough electric fields to start generating noise in the amplifier? A complete schematic, as well as components values for the power supply will be greatly appreciated, Thank you so much in advance.

From my understanding re: Great project; thank you for sharing.

Thanks for your answer. Probably 1 volt too?

I then switched to a 3 amp Slo Blo and every thing works fine. All the best John Reply. Thanks for your reply, Robin! With the right layout and component selection, you can build an excellent sounding Hi-Fi audio datasheey that will rival high-end amps retailing for several thousand dollars or more.

At first, the sound stage seemed too narrow to me and some of the songs sounded somehow odd — mostly metal tunes, in some the mids sounded somehow hollow. Evan on June 2, at 3: My suggestion would be to not just follow the instructions, which are very well explained, but to take full advantage of the instructions as a starting point to a better understanding of exactly what each component is doing.
