A Class A // Class AB amplifier rated 100 Watts when driving a 4 ohm loudspeaker. This circuit developed out of my 30+ years of JLH class-A based investigations. The original `simple` 1969 JLH class-A design provided excellent first cycle accuracy through mid and high frequencies (dynamic clarity) because there were no stabilisation components nor a series output choke, whilst the NFB error correction was established via the input emitter (some describe this as current feedback).

This simple 10 watts audio power amplifier is designed for home-brewed purpose. It is based on an Audio Power Amplifier IC that is called TDA2030. It is a monolithic integrated circuit in Pentawatt package, intended for use as a low frequency class AB amplifier. The TDA2030 provides high output current and has very low harmonic and cross-over distortion (0.2% at full load).

The circuit uses the TDA2030 which is a monolithic integrated circuit in Pentawatt® package, intended for use as a low frequency class AB amplifier. Typically it provides 14W output power (d = 0.5%) at 14V/4Ω; at ± 14V or 28V, the guaranteed output power is 12W on a 4Ω load and 8W on a 8Ω (DIN45500). The TDA2030 provides high output current and has very low harmonic and cross-over distortion.

This circuit may be used where a high current is required with a low ripple voltage (such as in a high powered class AB amplifier when high quality reproduction is necessary), Ql, Q2, and R2 may be regarded as a power darlington transistor. ZDl and Rl provide a reference voltage at the base of Ql. ZDl should be chosen thus: ZDl = Von-1

To set the above amplifier up, set R1 to max and R12 to 0. After doing this successfully, power on the amplifier. Set R1 so that the measured output offset is between 30 and 100mV. Once set, adjust R12 slowly to achieve a quiescent current of around 120mA. Keep checking the quiescent current as the amp heats up as it might change due to voltage dr
