Amplifier driver circuit diagram using transistors C5198 and A1941

Electronics Help Care October 23, 2026 Amplifier Diagram

This is an amplifier driver circuit diagram using transistors C5198 and A1941. It’s a mono circuit diagram. For stereo, we have to use a dual circuit board. We can use a minimum of 25-0-25 volts to 80-0-80 volts. It’s an incomplete circuit board. It’s only a driver circuit board.

We have to use the main amplifier transistors. like 2sc5200 and 2sa1943. We can also use C5198 and A1941 transistors. 2SC5200 and 2SA1943 transistors can produce a maximum of 150 watts. And C5198 and A1941 can produce a maximum of 100 watts of output. Please use a heatsink for the driver transistors. last 2 transistors can be hot. For this, the transistors need a heatsink.

Every amplifier needs a good voltage and current to produce the best audio output. This circuit needs dual voltage. Positive, negative, and ground voltages. We know that voltage × current = watts.
