Most designs have extensionrods are used between the pcb and the controlknobs at the front, to obtain a better internal layout. I take may hat off to you Robert. Is there any reason why the input capacitor C1 has such datasheet huge voltage rating well above the theoretical maximum of I have a question though.

I noticed that in the schematic you have a nF cap Csn. Thank you for this really great article.

Thanks for all the hard work. Thank you for your excellent work on this guide. In order to bring this down to a more reasonable level, I decided on using 4. The feedback loop should be kept as short as possible to reduce the loop area.

If I am correct the pcb layout needs to be modified to represent the difference in size between the 50pf and the pf all the best Reply.

Sorry to hear that… Try checking your spam folder. Brad on November 15, at 5: All the best John. The finished boards look great.


Francois on November 5, at 1: However, due to lack of deep knowledge in electronics, the project was lagging behind.

First off — thank you for the great tutorial and the breakdown of each step. Notify me of follow-up comments by email.

Download my parts list to see the components I used to get great sound quality from this amplifier. Although its a bit more work, I prefer the T version for the 0. I found the post about LM amplifier. I highly recommend reading the datasheet before building your amplifier. Do they have any kind of records on that so it may only require a push of a button on this end?

Angelo on August 25, at 6: Pietro Di Zinno on April 3, at 1: But the question is if the motors operation would datasehet enough electric fields to start generating noise in the amplifier? I was wondering the same thing.

Robert Reed on October 31, at 1: Circuit Basics on June 19, at 6: With the knowledge and the tools available on this site I have built very modified boards. Please double check the information below, as I do not have alot of knowledge about electronics yet I am a newbie. datsheet

Application note AN has additional information that fills in gaps left out of the datasheet. Meaning, small caps closest to LM Alessandro Raco on December 23, at Robin P Clarke on May 29, at I have just a question: Also, I would try to slide the capacitors away from the heatsink more on the PCB design so that the modules would have datashee longer life in many years time before breakdowns.


Consent to store personal information: If I am correct the pcb layout needs to be modified to dataeheet the difference in size between the 50pf and the pf. A very nice explanation.

Does anyone have a rough cost of building this amp?? Keep all unregulated storage caps close to the LM with proximity based on parasitic inductance effects.

There are two schools of thought here. 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 This will give good protection to the actual amp circuit but will not blow for shorted bridges or lytics!

Or is it just because the part is only manufactured like that by Mundorf? Leave a reply Cancel reply Your email address will not be published. You explain in the tutorial and as the actual photo of the cap shows the datashest value of the polypropylene is.
