The transistor amplifier circuit is provided with an oscillation preventing countermeasure. When a transistor (TR1) having a relatively high input capacitance is driven by another driving transistor (TR2) an oscillation preventing diode( D1 and /or 50) is connected to the connecting wire of both the transistors(TR1,TR2). Current communication necessary between the capacitance between the collector and the base of the transistor (TR1) and the inductance due to the length of the wire can be prevented by the rectifying action of the oscillation preventing diode (D1,50).thereby preventing oscillation of the transistor amplifier circuit.
