Uhf amplifier for 400 850mhz using a 2sc3358 transisor. Stereo amplifier schematic only. 1 8 mhz 18 mhz 5w bd139 power amplifier w8diz. 14w audio amplifier schematic only.

80w stereo amplifier schematic only. In other words a power amplifier amplifies the power of the input signal which is why these types of amplifier circuits are used in audio amplifier output stages to drive loudspeakers. The higher the voltage across r e v e the more temperature stable the amplifier but the more power will be wasted in r e due to v e 2 r e as well as the decreased ac signal gain if r e is not bypassed by a low reactance capacitor. High power amplifiers up to 100w.
