Review YAMAHA Resistor #kr105-03 #287-81911-10-00 fits HS1 HS1B 1970-71

The Yamaha 287-81911-10-00 1970-71 HS1 HS1B Resistor Kr105-03 is an essential electrical component for various applications, particularly in vintage Yamaha electronic equipment from the 1970-71 HS1 series. This resistor is specifically designed to meet the unique electrical requirements of these vintage systems.

This resistor is a 5-watt, 10k Ohms, 1/4-watt, carbon composition type. Its resistance value is 10,000 Ohms, making it suitable for voltage dividing, current limiting, or terminating applications. The resistor is rated for a maximum power of 5 watts, which ensures reliable performance under normal operating conditions.

The resistor's size is 1/4-watt, which is a standard size for many electronic components. Its length is approximately 1.5 inches (38.1mm), and its width is around 0.5 inches (12.7mm). The resistor is cylindrical in shape, with a diameter of approximately 0.25 inches (6.35mm), making it easy to install in various electronic circuits.

The resistor's color code is Kr105-03. The first two digits "Kr" represent the resistor material, which is carbon composition. The third and fourth digits "105" represent the resistance value, with the first digit "1" indicating a 10k Ohms resistance value, and the second and third digits "05" indicating a fifth decimal place value of 0.5 Ohms. The last digit "3" represents the tolerance level of the resistor, which is plus or minus 3% from the stated resistance value.

This resistor is suitable for use in high-voltage and high-current applications, making it ideal for use in vintage Yamaha electronic equipment. Its carbon composition material provides excellent stability and temperature coefficient, ensuring consistent resistance values over a wide temperature range.

Installation of this resistor is relatively straightforward. It can be mounted directly onto a heat sink or printed circuit board using its threaded metal end. The resistor's resistance value can be measured using a multimeter to verify its accuracy before installation.

In summary, the Yamaha 287-81911-10-00 1970-71 HS1 HS1B Resistor Kr105-03 is a vital electrical component for vintage Yamaha electronic equipment from the 1970-71 HS1 series. Its 5-watt, 10k Ohms resistance value, 1/4-watt size, and carbon composition material make it suitable for high-voltage and high-current applications, ensuring reliable and consistent performance in various electronic circuits.

The Yamaha HS1 and HS1B are powered studio monitors known for their accuracy and flat response. These monitors use resistor networking for their crossover circuit, and one of the resistors required is the Kr105-03. Here are some pros and cons of buying this specific resistor for your Yamaha HS1 or HS1B.

1. Authenticity: By using the exact same resistor as the one originally used in the HS1 and HS1B monitors, you can ensure that the replacement part will provide the same electrical characteristics as the original.

2. Improved sound quality: Replacing a faulty or degraded resistor can help restore the monitor's original sound quality, ensuring that your mixes translate accurately to other systems.

3. DIY repair: If you enjoy working on electronic equipment or are a professional audio engineer, having a spare Kr105-03 resistor on hand can save you the cost of sending the monitors to a repair shop.

1. Cost: Buying a single resistor may seem expensive, especially if you're only replacing one component in your monitor. However, considering the importance of accurate sound reproduction in a studio setting, the investment in a high-quality replacement part can be justified.

2. Availability: Depending on your location and the availability of stock, it may take some time to source and receive the resistor. Additionally, some retailers may charge higher prices for the part due to demand or shipping costs.

3. Risk of damage: Handling and installing electronic components can be risky, especially for those without experience. Improper installation or mishandling of the resistor could potentially damage other components in the monitor or even the resistor itself.

The decision to buy the Yamaha 287-81911-10-00 Kr105-03 resistor ultimately depends on your specific situation. If you're a professional audio engineer or studio owner, having a spare resistor on hand for repairs or maintenance can be invaluable. On the other hand, if you're a home user or hobbyist, the cost and availability of the part may make it a less attractive option. However, considering the importance of accurate sound reproduction, investing in a high-quality resistor can help ensure that your Yamaha HS1 or HS1B monitors continue to perform at their best.

If you decide to purchase the Kr105-03 resistor, it's important to ensure that you buy it from a reputable supplier to ensure authenticity and quality. Check reviews and ratings from other customers to ensure that you're getting a genuine part. Additionally, consider purchasing the resistor in bulk or as part of a larger order to save on shipping costs and take advantage of volume discounts.
