Here you go guys, I have three (3) Audio Hardware Starters (AHS) fully completed and functional designed that I am recommending for absolutely beginners in DIY (do-it-yourself) Audio Amplifier Build with class AB and Class D.

Integrated Circuit : LM1876 by National Semiconductor [DR20W Stereo Class AB DIY Amplifier ]  – Here are reasons why I am recommending this :

  1. 99.9% easy & success build
  2. Plug and Play with no further tuning
  3. abundant technical resource
  4. Circuit Description, Assembly & Testing
  5. explained in Taglish (Tagalog-Filipino)
  6. Industry standard PCB FR-4
  7. Hardware full-package (except the Transformer)

the kit that I prepared for easy hardware build

Discrete Design : DNY40W Class AB [40W Mono DIY Amplifier ]– Here are reason why I am recommending this :

  1. 99.7% success build
  2. brewed by audio hobbyist by @ www.elab.ph for diy learning
  3. abundant technical resource
  4. Circuit Description, Assembly & Testing
  5. Explained in pure English, demo Video @ youtube
  6. Industry stanbdard PCB FR-4
  7. Hardware full-package with kit version for easy component source

I recommend this for your discrete audio amplifier adventure as it was proven in terms of (1) Electrical functionality (2) ample Technical documentation (3) Assembly (4) Testing and (5) good sounding performance when paired with a good speakers and nice music source, as we often heard “small but terrible”.

I love it and I am proud of it, I created a dedicated youtube channel for demos, discussion and shows

Many thanks to the dny40wTEAM :

  1. Project Manager : F. Dandy M.(Baguio, Philippines)
  2. Hardware Design : Danny E. (Seattle USA)
  3. PCB Design : Arnel R.(KSA)
  4. Build : Michael A. (Tian Jin, China)
  5. Testing / Reliability : Ariel A. (Taiwan/S. Korea)
  6. Procurement : Richa / Anna (Shenzhen, China)

DR100W conCEPT Class D TDA8920BTH / TDA8950BTH Stereo DIY Amplifier ]– its digital PWM amplifier (Pulse Width Modulation). Here are reason why I am recommending this :

  1. 100 % easy & success build
  2. Plug and Play with no further tuning
  3. abundant technical resource
  4. Circuit Description, Assembly & Testing
  5. Explained in English with video demo and discussion
  6. Industry standard PCB FR-4
  7. Hardware full-package ( extended learning with Hybrid analog + digital Equalizer & Tone Controls).

So far, this conCEPT is one of the best I can recommend for starting with Class-D digital power amplifier. It will not only talking about class-D amplifier but the whole system including tone Equalization, Man Machine Interface (MMI) or Human Machine Interface (HMI) as often people called it like displaying and how the amplifier communicates to the User, Testing, modifications, improvement and other stuff – its a full pack learning.

I created a dedicated youtube channel for this
