Review SANSUI Eight Original And Driver Transistors Pair

The Sansui 2SA566 and 2SC680 driver transistors are high-performance electronic components widely used in various audio applications, particularly in the design of power amplifiers and preamplifiers. These transistors are manufactured by Sansui Electric Co. Ltd., a renowned Japanese electronics company known for its high-quality audio components.

The 2SA566 is a NPN power transistor that comes in a TO-3 case, allowing for efficient heat dissipation. It has a continuous collector current of 25 amperes and a maximum collector-emitter voltage of 100 volts. The transistor's high current gain (hFE) of approximately 250 ensures efficient amplification of the input signal. It also boasts a low on-state resistance (Rds(on)) of 0.13 ohms, which minimizes power loss and contributes to the transistor's high power efficiency.

The 2SC680, on the other hand, is a PNP power transistor that comes in the same TO-3 case. It has a continuous collector current of 20 amperes and a maximum collector-emitter voltage of 100 volts. The transistor's high current gain (hFE) of approximately 250 also ensures efficient amplification of the input signal. Its low on-state resistance (Rds(on)) of 0.19 ohms is slightly higher than the 2SA566 but still contributes to the transistor's high power efficiency.

Both transistors have a maximum thermal junction temperature rating of 150 C, ensuring reliable performance even under demanding conditions. They are also RoHS compliant, making them environmentally friendly options for electronic designs.

The Sansui 2SA566 and 2SC680 driver transistors offer excellent power handling capabilities, high efficiency, and excellent current gain, making them excellent choices for power amplifier designs in professional audio equipment, home audio systems, and even in some high-end audio applications where high power and high fidelity are critical. Their TO-3 case design ensures efficient heat dissipation, maintaining a stable operating temperature and contributing to the longevity of the transistors.

Sansui 2SA566 and 2SC680 are vintage transistors that were popularly used in audio amplifiers due to their excellent sound quality. Here are some pros and cons if you're considering buying these transistors:

1. Warm and natural sound: These transistors are known for their ability to produce a rich, warm, and natural sound that is preferred by many audiophiles.

2. Vintage tone: Sansui transistors have a unique tonal character that is not found in modern transistors. This can add a desirable vintage tone to your audio system.

3. Durability: These transistors are well-built and durable, making them a good investment for those who value long-term reliability.

4. Availability: These transistors are widely available on the secondary market, making them relatively easy to find.

1. Limited supply: Due to their age, the supply of Sansui 2SA566 and 2SC680 transistors is limited, which can drive up their prices.

2. Compatibility: These transistors may not be compatible with modern audio equipment, and may require modification or additional components to work properly.

3. Higher cost: Compared to modern transistors, vintage transistors like Sansui 2SA566 and 2SC680 can be more expensive.

4. Risk of damage: Vintage transistors like these can be fragile and may require careful handling to avoid damage during shipping or installation.

Buying Sansui 2SA566 and 2SC680 transistors can be a worthwhile investment for audiophiles who value warm, natural sound and vintage tone. However, these transistors may not be the best choice for those who prioritize compatibility with modern equipment or a lower cost. Additionally, the limited supply and risk of damage can add to the challenge of acquiring and installing these transistors.

If you're considering buying Sansui 2SA566 and 2SC680 transistors, it's important to do your research and ensure that they will work properly with your audio equipment. You may also want to consider purchasing them from a reputable dealer or seller to minimize the risk of damage during shipping. Ultimately, the decision to buy these transistors should be based on your personal preferences and priorities as an audiophile.
