Review HICKOK Tube Tester Restored Calibrated Audio Ham Radio

The Hickok 539A Tube Tester is a robust and highly capable audio test instrument designed specifically for ham radio enthusiasts and professional technicians. This device is a true workhorse, equipped with features that allow for comprehensive testing of various types of vacuum tubes, including triodes, tetrodes, pentodes, and beam tetrodes.

The Hickok 539A boasts an impressive frequency range of 20 Hz to 30 MHz, making it versatile enough to cover a wide range of audio applications. The tester features a high-resolution, analog meter that provides real-time readings of tube parameters such as plate current, grid voltage, plate voltage, and grid leakage. The meter is backed by a precision AC voltage source and a DC current source, ensuring accurate and reliable test results.

One of the standout features of the Hickok 539A is its ability to perform both AC and DC tests. The AC test mode allows for the measurement of tube gain, input and output impedance, and phase shift. The DC test mode, on the other hand, is used to check tube parameters such as plate voltage, plate current, and grid leakage.

The Hickok 539A also includes a built-in oscillator, which is particularly useful for testing tube amplifiers in the audio frequency range. The oscillator can be used to inject a signal into the amplifier and measure its output characteristics, such as gain, distortion, and frequency response.

The device is housed in a sturdy, metal chassis, featuring a user-friendly front panel with clearly labeled controls and indicators. The Hickok 539A is powered by a 115V AC input, and it includes a built-in fuse to protect against electrical surges.

In conclusion, the Hickok 539A Tube Tester is an essential tool for any ham radio enthusiast or professional technician working with vacuum tubes. Its wide frequency range, high-resolution meter, and comprehensive test capabilities make it a reliable and versatile device for diagnosing and repairing audio equipment.

For those who are new to ham radio or vacuum tube testing, or who have limited budgets, there may be more cost-effective and user-friendly options available.

Details:

I bought this 3 years ago from the local tech who did work. But I just don't need it anymore. I am not a tube guy just ham radio operator. Its a fine, accurate machine.

The case is just average looking with plenty of nicks and dings in covering. The front panel has been cleaned to be almost sparkling.

Buyer pays actual mailing cost. I have used it a fair amount for testing tubes in vintage ham radios and antique broadcast. Please look at the pix and ask questions.
