200W audio amplifier PCB Audio power amplifier components IC1, IC2 = 2 IC’s TDA2030 T1, T3 = 2 transistors KT818 or BD708 T2, T4 = 2 transistors KT819 or BD705 C1, C2, C3, C4, C7 = 5 capacitors 150 nF ...

In the simple circuit shown in Figure 9.9 (the case shown is for an NPN transistor, but a virtually identical circuit, but with negative supply rails, could be made with a similar PNP transistor), the ...

They’re no good for audio but find a use in RF power amplifiers, where LC circuits filter out the resulting harmonics.) A Fully Digital Audio Amplifier: Class D ...
