Nathan Amp Series
For fellows diyer’s and Audio Hardware Start-up / Starter who are looking for a :
- good sounding Hi-Fi amplifier (I don;t mean super strong)
- class-AB discrete design
- diy-c and circuit playground,
this project is for you.
The Nathan Amp project is a series of amplifier configuration following the concept of Audio Discrete Design Hardware Startup or simply STARTERs in Audio Amplifier discrete “transistorized” desing:
- Simple : Nathan Amp ID40, 40Wrms per channel @ 8 ohms
- Standard : Nathan Amp Baby, 100Wrms per Channel @ 8 ohms
- Rugged : Nathan Amp Train, 1000Wrms per channel @ 4 ohms (the experimental version)
Here is the video introduction to the Project :
Hardware Startup / Starter
Here is what I proposed in the name of Learning and as an Audio Discrete Design Hardware Startup (AD2HS).
Start with the Nathan Amp ID40, which is a basic circuit and with a power supply of +/-30Vdc, which is good enough to provide a concert level to your home with true power of 40W average (or rms power) into 8 ohms speaker. From the knowledge you learned, it will sky-rocket you to re-design Nathan Amp ID40 into a Nathan Amp Baby with 100Wrms into 8 ohms speaker load.
Functional Test with Live Music
Here is the casing assembly video below. I rushed to make the aluminum casing because I wanted to test some parameters which i can only do it while on the casing, like S/N (signal to noise), stereo separation, power capability when both channels were driven.
