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 Bearing in datashheet most is subjective, though differences between components of different materials do have a definite measurable difference e.

The two silver mica capacitors 47pF and pF appear to be reversed in your pictures. I could send them to you lm8386tf the amount of the postage.

Robert Thank you very much for the reply. Dave on October 30, at 8: I found the post about LM amplifier. We can use the F c equation with R i and C i:.

In there you could put things like a publishing date and a copyright notice, keywords, a table of contents, social link URLs written in full as l3m886tf text instead of just blue words in the article, etc. Fusing both AC line input and power rails are the best but more work and expense. What could be wrong?

Keep all unregulated storage caps close to the LM with proximity based on parasitic inductance effects.

A Complete Guide to Design and Build a Hi-Fi LM Amplifier – Circuit Basics

Vince on February 7, at Your LM article is fantastic. John- in regards to the case, the T version is non isolated meaning the back of the case is clean metal connected directly to the -V supply which requires electrically insulating it from the heat sink. Could you update this info. Due to the length of this post, I decided not to cover the power supply in detail, but I may do so in the future. I signed up for the partslist but I am not recieving any partslists, can someone upload the partslist, thank you.

Asok Sen on February 7, at 6: George Riad on February 3, at 5: Mustafa Kamal on November 17, at Low current grounds are the ground feeds to the input circuitry and dtasheet loop. In this arrangement, the heat sinks provide some shielding from the Thiele networks and the AC wires leading to the transformer:. I am asking for information by email desoto wp. Im beginning to not trust this beast. There are many circuits on the net but again they do not explain any design aspects completely.

Thank you for this really great article. You seem to know what you are doing as well as having a lot of experience. Im considering building the amp, but i have a question that i sadly havent found an asnwer to.

Thanks a million for the detailed lm388tf quality guidance. Hi All, someone correct me if I am wrong, the photo showing the board shows the pf in place of the 50pf as is the board lay out.

You could even add a DIV at the top of the web page with a. I sure hope I got genuine chips as I ordered them from Mouser. Datasheft like the way you treat ground connections.

Brian Stover on January 28, at From then on, I have been trying to improve its performance by making modifications. The thermal resistance of the T version including mica insulator and paste is about 1. Notify me of new posts by email. I can hear details in songs that I never knew were there. Please double check the information below, as I do not have alot of knowledge about electronics yet I am a newbie. Hi all my 51pf silver mica is definitely much smaller than the pf silver mica I have so….?

In the rest everything is lm388tf to the circuit.

First being to place fuse at bridge input, which will protect all power supply components. I noticed that in the schematic you have a nF cap Csn.

However If amp is run at near full load not likely heating effects of the transformer and bulk storage caps should be cooled as well. Sound quality is severely compromised when the SPiKe circuitry is enabled, so to prevent this we need a heat sink with a thermal resistance low enough to dissipate the maximum power dissipated by the LM If I may offer my observations, which are purely subjective though based and no doubt influenced by research.
