DLH Amplifier-Trilogy with PLH and JLH Amplifiers
### DESCRIPTION
This very simple design has all the ingredients to satisfy even the most demanding DIYers. The output power in pure class A operation is 15.52 W at 2 ohms and 1 KHz, or 7.76 W at 4 ohms and 1 KHz, or 3.88 W at 8 ohms and 1 KHz. THD is only 0.025 % at 15.52 W and 1 KHz (2 ohms). THD is only 0.0024 % at 7.76 W and 1 KHz (4 ohms). THD is only 0.00091 % at 3.88 W and 1 KHz (8 ohms). Voltage gain = 8,9 dB.
Only two stages. Four transistors. Very few components. Its performance is surprisingly good, despite its total simplicity.
High bandwidth. Ultra low distortion. Input in single ended configuration. Output in single ended or push pull configuration, entirely adjustable by the position of a trimpot. PSRR: 61 dB across the entire audio bandwidth.
