Review NATIONAL Electronics Thyratron Power Tube

The National NL-678 Thyratron Power Tube is a vintage and hard-to-find electronic component that serves as a high-voltage switch in various electronic circuits. This particular thyratron, manufactured by the National Electrical Manufacturing Company, is a type of gas-filled triode tube.

The NL-678 Thyratron boasts a high-voltage rating of 1200 volts and a maximum power dissipation of 15 watts. Its filament voltage is 12.5 volts, and the filament current is 0.15 amperes. The NL-678 has an anode current rating of 0.05 amperes, a cathode current rating of 0.1 amperes, and a maximum operating temperature of 150 degrees Celsius.

This thyratron tube measures approximately 5.5 inches long and 2 inches in diameter, making it a substantial component in any circuit it's used in. The NL-678 Thyratron Power Tube is commonly used in high-voltage applications such as ignition systems, radar, and x-ray equipment.

Despite its age, the NL-678 Thyratron Power Tube is still a valuable tool for hobbyists, collectors, and electronics enthusiasts who work with vintage electronics or are building replica circuits. However, due to its rarity, it may be more challenging to find and more expensive compared to modern electronic components. Nevertheless, the NL-678 Thyratron Power Tube's unique features and historical significance make it an essential piece in any vintage electronic component collection.

1. High Voltage and Current Handling Capability: NL-678 thyratron tubes are designed to handle high voltages and currents, making them suitable for applications requiring high power handling capabilities.

2. Long Life Span: Thyratrons, in general, have a longer life span compared to other vacuum tubes, reducing the need for frequent replacements.

3. Reliability: Thyratrons are known for their reliability and can operate under harsh conditions, making them a good choice for applications where reliability is crucial.

4. Wide Operating Range: NL-678 thyratrons can operate over a wide range of temperatures and voltages, providing flexibility in their use.

1. Limited Availability: Thyratrons are not as commonly used as other types of vacuum tubes, making them harder to find and more expensive.

2. Complex Maintenance: Thyratrons require more complex maintenance than other types of vacuum tubes, including regular alignment and replacement of electrodes.

3. Limited Application: Thyratrons are not suitable for all types of applications, such as audio amplifiers or high-frequency applications.

4. Large Size: Thyratrons are larger and heavier than other types of vacuum tubes, making them less suitable for applications where space is limited.

NL-678 thyratron power tubes offer high voltage and current handling capabilities, long life span, reliability, and a wide operating range. However, they are less commonly used, more expensive, require complex maintenance, have limited availability, and are not suitable for all types of applications.

If you require high power handling capabilities, reliability, and can accommodate the larger size and more complex maintenance, then NL-678 thyratron power tubes can be a good choice. However, if you are looking for a more commonly used, less expensive, and easier to maintain vacuum tube, then other types of tubes may be more suitable. Consider your specific application requirements before making a decision.
