Review HICKOK Antique Tube Tester Western Electric Working Condition

The Hickok 5727 Antique Tube Tester is a rare and highly sought-after piece of vintage electronic equipment that was originally manufactured by the Hickok Instrument Company around the 1940s or 1950s. This tube tester was specifically designed for testing and evaluating the performance of vacuum tubes, which were the primary electronic components used in radios, televisions, and other electronic devices during that era.

The Hickok 5727 tube tester is a benchtop instrument that features a robust and sturdy construction, with a metal casing and a wooden base to help reduce vibrations and ensure accurate readings. The front panel is adorned with a multitude of knobs, switches, and meters, providing an array of testing functions and parameters.

From left to right, the first row of controls includes an I-V selector switch for selecting the type of test to perform - either Mid-Plate or Grid tests. The "Bias" control knob allows for adjustment of the test bias voltage, while the "Variac" switch provides the ability to apply a variable voltage to the grid for more precise testing. The "Grid Range" switch offers several options for selecting the appropriate grid voltage range.

Moving to the right, a series of switches control the probe connections for the specific type of tube being tested. Depending on the tube model, the user can select between directly heating the filament, using an external filament supply, or testing the tube without heating. Additionally, other switches permit testing of the filament voltage and the visual inspection of the filament.

The center portion of the instrument houses the tube tester's testing meters and oscilloscope. A comprehensive collection of meters offer readouts for various testing parameters such as plate current, grid current, plate resistance, grid voltage, and filament voltage. The two oscilloscope cathode ray tubes allow for visual inspection of waveforms and conductivity tests.

The base of the instrument features a protective rubber feet and a power cord. The power supply compartment offers numerous fuses, voltage selector switches, and ammeter readouts to monitor power consumption during testing.

This piece of vintage test equipment is a true gem for electronics enthusiasts, collectors, vintage radio and television restorers, and hobbyists.

Details:

It had been sitting in his storage unit for over 20 years. It has the original owners manual as well. Amazingly the thing actually works. Only thing it requires is a fuse light bulb.
