The power supply and each of the individual components do have a massive influence, especially as there are so few of them. George on October 19, at 8: However the big lytics will continue to conduct until fully discharged and continue to do damage for faulty down stream components. Congratulations and thanks for the details.

Dr Dorkmeister on May 21, at Application note AN has additional information that fills in gaps left out of the datasheet. I will add a comment to this post: You can datasheeet an input selector knob if you want more inputs on the same controls-pcb and then mount the pcb parallel to where your control knobs should be. And lk3886tf I am left with these choices. If a separate supply is provided for each channel with separate capacitors bank for each channel, or even possibly with two power transformershow should grounding be organized?

Hi, I really enjoyed reading this! The capacitor is there to filter any radio frequencies picked up by the chassis.

Howeveris it possible to go directly to EDA with info you posted for the amplifier board? I just finished my build based on your tutorial, with minor changes.

Consent to store personal information: Your efforts really appreciatedā€¦. I assembled the circuit exactly like the one in the guide, with the following changes in the PSU: Keep all unregulated storage caps close to the LM with proximity based on parasitic inductance effects.

Congratulations for the excellent post! True nice complete job! Download my parts list to see the components I used to get great sound quality from this amplifier. I then switched to a 3 lm38866tf Slo Blo and every thing works fine. The main system ground connects to the ground protection circuit discussed belowwhich then connects to the chassis.

datzsheet If you want to add controls to your amplifier, design your controlscircuit of similar high quality as the munford components and circuit designs used. To convert voltage gain to decibels db gain, use this formula:.

Second is to place fuse at the output end of the lytics. I started with 1.

Commonly available through Moser and DigiKey. I used solid core 22 AWG, which works well because it can be twisted into a tight coil. Sascha on April 25, at 7: Which voltage level gives this output?

And I have a few questions: All other 47 pages of the article and the comments are hidden. The datasheet gives a value of 2.

John on August 15, at 3: Thus, I was wondering if you could state the specifications of your amp, distortion and noise characteristics so it can be compared to other LM designs, so see if one needs to improve anything.

Victor H Faucheret on March 27, at You catasheet even add a DIV at the top of the web page with a. Talk to you next timeā€¦.

Judah on October 4, at You can also check out this video to see a quick overview of the design process. Both the lm and the lm which are both very impressive. The thermal resistance of the T version including mica insulator and paste is about 1.

The TF version is isolated and mounts directly to the heat sink. Under normal operating conditions, low voltage ground loop currents flow through the resistor R1 to earth the chassis.
