Alessandro Raco on December 23, at Khurrum on September 21, at 9: A lot of effort obviously went into this.

The main system ground is located as close as possible the reservoir capacitors on the power supply.

Phil on May 12, at 5: But the question is if the motors operation would generate enough electric fields to start generating noise in the amplifier? Rb before Rin or Rin before Rb?

Success with the build, Ed. A bit much perhaps?

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

I used single sided PCB, but tried sticking to your layout as closely as possible and changed some pm3886tf — especially the Mundorfs for something readily available and a bit cheaper. Does anyone have a rough cost of building this amp?? Which voltage level gives this output?


Talk to you next time…. I was wondering the same thing. Whats up lm388t6f that. Thanks for the help! All the best John Reply. Cant wait to see post on power supply! I can use it, no?

With two two separate power supply units, all grounds be channel specific on the PCBs and the two ground-loop protection circuits one from each power supply unit PCB connected together to the chassis? Which is close enough to 27 db, and above the Most of the time the controls pcb will be mounted parallel towards the front of the lm3886f.

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. I calculated the total cost of accuiring these exact components in The Netherlands europe: Dave on September 6, at 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. Thank you for sharing this documented design guide for LM This setup drives them quite well.

In addition, I wanted to publish a systematic article with instructions on that. It explained so much. 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 ratasheet to improve anything.

The PCB has 2 holes for the diodes, but the parts list specifies a 3 pin diode. Jimmy George on August 23, at 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 normal text instead of just blue words in the article, etc.

Thanks for your answer. The thermal resistance of the T version including mica insulator and paste is about 1. I would like to better understand how to set a value for low-frequency cutoff at the feedback loop.
