Common everyday complementary power darlington transistors will substitute for these. They need to be rated at 75 watts or higher, 5 amps for higher, and 80 volts or higher. Good examples of these are the TIP142 (NPN) and TIP147 (PNP), which are …
30W Audio Amplifier Using NE5534 & Darlington …

Here, we use an NE5534 operational amplifier and two Darlington transistors (TIP141 and TIP146) to produce a 30W audio amplifier. NE5534 was selected because it has maximal working power supply up to ±22V, significant bandwidth, low total harmonic distortion (THD), high slew rate and output current more than ±20mA. Circuit and working
