A Comparative Analysis of the Hickok 639B, Hickock 539B, and Paul Hart Tube Testers

The Hickok 639B, Hickock 539B, and Paul Hart tube testers are popular choices for technicians and hobbyists seeking reliable and effective tools for testing vacuum tubes. In this analysis, we will compare these three models based on their features, advantages, and disadvantages to help you make an informed decision.

1. Advanced features: The Hickok 639B offers automatic testing for various types of tubes, including power tubes, and provides accurate measurements for parameters like plate current, grid current, grid voltage, screen voltage, anode voltage, grid leakage, and plate leakage.

2. Durability: Known for its ruggedness and longevity, the Hickok 639B has remained a popular choice for many years.

3. Limited compatibility: The Hickok 639B may have difficulty testing some newer tube designs, as its test circuitry predates some of the more modern scattering parameters.

1. Complexity: The Hickok 639B's many features and controls may be overwhelming for beginners or users that only need basic testing capabilities.

2. Size and weight: The tester is relatively large and heavy, making it less portable compared to some other models.

1. Versatility: The Hickock 539B is compatible with a broad range of tube types, including power, audio, and non-vacuum tubes. It's also capable of measuring parameters like resistance, capacitance, and inductance.

2. Adjustable voltage and current: Unlike the Hickok 639B, which employs automatic testing, the 539B allows manual control of testing voltages and currents, making it a better choice for those who prefer a more hands-on experience.

1. Complexity: Similar to the Hickok 639B, the 539B can be complicated for beginners due to its numerous controls and features.

2. Size and weight: Although smaller and lighter than the Hickok 639B, it is still a larger and heavier device compared to some other modern tube testers.

1. Simplicity: Paul Hart tube testers are known for their user-friendly designs and straightforward testing procedures, making them an excellent choice for beginners and those who prefer a more streamlined testing experience. They offer tests for plate voltage, screen voltage, filament voltage, and audio output.

2. Portability: Most Paul Hart tube testers are compact and lightweight, making them highly portable compared to larger models like the Hickok 639B and 539B.

1. Limited capabilities: Paul Hart testers only offer basic testing capabilities, which may not be sufficient for complex tube diagnoses or advanced applications.

2. Limited compatibility: While Paul Hart testers can test various types of tubes, they are not suitable for all tube designs and may not provide accurate test results for some modern tube types.

Each of these tube testers possesses unique advantages and disadvantages. The Hickok 639B and 539B offer advanced features, accuracy, and testing capabilities but can be complex and bulky. Paul Hart tube testers cater to a more simplistic and portable testing experience but sacrifice some advanced capabilities.

Based on the information presented, the ideal choice depends on your specific needs and experience level. Power users, professionals, and advanced hobbyists seeking high test accuracy and advanced capabilities would likely prefer the Hickok 639B or 539B. Simpler and more portable options would be suitable for beginners or those that only require basic testing features. Inspect the offered models in detail, considering their features, costs, and your personal needs, to make the best decision for your tube testing requirements.
