Medium Power-Driver

Looking for really good driver transistors for a bipolar power amplifier design? With their exceptionally linear gain characteristics, Sanken's 2SA1668/2SC4382 deliver less distortion and better sound compared to the competition. For a lateral MOSFET amplifier you are better served with Sanyo's 2SA1209/2SC2911. Why? The low output capacitance (Cob) of these devices translates to reduced "Miller" effect, resulting in lower distortion.
