Could you also consider doing a solid state discrete power amp datazheet dual dc power supply. Robert on July 21, at 9: Hope the above was helpful.

Hi, I really enjoyed reading this! Audio input cables running from the source to the amplifier chassis can pick up interference.

Truly fantastic stuff you got here! Though I have no expertise in Physics, was able to understand the technical things in this article. George Riad on February 3, at 5: If there were a way to trade email addresses, I think that I have a few of the amplifier boards in my shack.

Success with the build, Ed Reply.

If you want to add controls to your amplifier, design your controlscircuit of similar high quality as the munford components and circuit designs used. Leave a reply Cancel reply Your email address will not be published. Does anyone have a rough cost of building this amp?? Lower than 2 to 4 Hz is ideal. In the rest everything is equal to the circuit.


The combination of bulk caps should provide low impedance current throughout the frequency band for the load.

The thermal resistance of the gap between the chip case and the heat sink. Meaning, small caps closest to LM Although your question is a year old, I will answer it with my assumptions so far after searching online with the same questions in mind.

Or did you order some other combination dstasheet heatsink and case? You explained it very well to me! Good luck, Ed Reply. I agree to let Circuit Basics store my personal information so they can email me the file I requested, and agree to the Privacy Policy.

This will give good protection to the actual amp circuit but will not blow for shorted bridges or lytics! Im considering building the amp, but i have a question that i sadly havent found an asnwer to. Dan, I dont remember but I dont think so. The datasheet gives a value of 2. I sure hope I got genuine chips as I ordered them from Mouser.

If I am correct the pcb layout needs to be modified to represent the difference lm3886gf size between the 50pf and the pf. Use the diagram below as a guide for wiring the various parts together:.

John on August 25, at 1: Use the metal tab version of the part.

You explain in the tutorial and as the actual photo of the cap shows the actual value of the polypropylene is. I assembled the circuit exactly like the one in the guide, with the following changes in the PSU: I xatasheet add a comment to this post: For the power supply circuit, how can I connect diodes and capacitors to safely give the required voltage and do away with the transformer.

Application note Lm38866tf has additional information that fills in gaps left out of the datasheet.
