1805 HICKOK Vacuum Tube Oscilloscope Dual Trace

Review HICKOK Vintage Rare Vacuum Tube Oscilloscope Model Dual Trace Works Read

The Hickok 1805 Vacuum Tube Oscilloscope is a vintage piece of test equipment, known for its exceptional performance and versatility. This dual-trace oscilloscope, manufactured by Hickok Instruments in the late 1950s, is a must-have for electronics enthusiasts, restoration projects, and educational institutions.

The Hickok 1805 features two separate trace channels, each capable of displaying signals in the voltage range of 10 microvolts to 100 volts with a time base that spans from 1 microsecond to 10 seconds. The horizontal time base resolution is 1 nanosecond, making it an ideal instrument for analyzing high-frequency signals.

The oscilloscope employs a pair of 6AL5 vacuum tubes that act as amplifiers and a 6AV6 beam deflection tube to display the signals. The instrument comes equipped with a set of standard probes, including X10, X100, and X1000 attenuators, enabling measurement of various signal amplitudes.

The Hickok 1805 sports a user-friendly front panel with multiple controls to manipulate the time base, triggering, and vertical sensitivity. A built-in signal generator can be used to provide test signals with adjustable frequency, voltage, and amplitude. The instrument also features a calibrated internal test signal source to ensure accurate measurement of input signals.

The oscilloscope is housed in a robust, metal cabinet with a clear glass front panel to allow easy viewing of the displayed signals. It has a built-in carrying handle, making it portable for lab use or demonstrations. The Hickok 1805 is a self-contained unit that requires only a line voltage (110-220VAC) to operate, with no external power supplies or cooling systems required.

The Hickok 1805 vacuum tube oscilloscope is a valuable addition to any electronics workbench, offering a unique blend of historical significance and functional capabilities. With its dual-trace capability, high time base resolution, and user-friendly design, this vintage instrument remains a favorite among electronics hobbyists and professionals alike.

The Hickok 1805 vacuum tube oscilloscope is a historic piece of test equipment, known for its high performance and dual trace capability. Here are some pros and cons that might help you decide if buying this oscilloscope is the right choice for you:

1. High Performance: The Hickok 1805 oscilloscope is known for its high performance and accuracy. It can handle frequencies up to 20 MHz and has a bandwidth of 1 MHz. This makes it suitable for testing and debugging a wide range of electronic circuits.

2. Dual Trace Capability: The dual trace capability of the Hickok 1805 oscilloscope allows you to display and compare two signals on the same screen simultaneously. This is a valuable feature for troubleshooting complex systems and identifying issues that might not be apparent when looking at one signal at a time.

3. Historical Significance: The Hickok 1805 oscilloscope is a piece of electronic test equipment history. It was first manufactured in the 1950s and has been used in laboratories and workshops around the world for decades. Owning one of these oscilloscopes is a great way to connect with the past and appreciate the evolution of technology.

1. Size and Weight: The Hickok 1805 oscilloscope is a large and heavy piece of equipment. It measures approximately 15 inches wide, 10 inches deep, and 6 inches tall, and weighs around 30 pounds. This makes it difficult to transport and requires a dedicated space for storage and use.

2. Tube Technology: The Hickok 1805 oscilloscope uses vacuum tube technology, which is less reliable and less energy-efficient than modern solid-state electronics. Tubes can burn out or fail, and they require a constant power supply to operate. This can make the oscilloscope more expensive to maintain and operate over time.

3. Limited Inputs: The Hickok 1805 oscilloscope has a limited number of inputs, which may not be sufficient for modern testing requirements. It has two input channels for the dual trace capability, and additional channels can be added using external probes or preamplifiers. This can add to the cost and complexity of using the oscilloscope.

The Hickok 1805 vacuum tube oscilloscope is a high-performance and historically significant piece of test equipment. Its dual trace capability, high bandwidth, and accuracy make it a valuable tool for troubleshooting and debugging electronic circuits. However, its size, weight, limited inputs, and reliance on tube technology make it less practical and more expensive to use than modern solid-state oscilloscopes.

If you are looking for a high-performance oscilloscope for general-purpose testing and debugging, a modern solid-state oscilloscope with a larger number of inputs and a smaller footprint may be a better choice. However, if you are a collector or historian interested in the history of electronic test equipment, or if you have a specific application that requires the dual trace capability of the Hickok 1805 oscilloscope, then it may be worth the investment. Just be prepared for the additional cost and complexity of maintaining and operating a vacuum tube oscilloscope.

Details:

The unit is an older and we did not go over every part, likely that some parts are at optimal performance, but as you can see the tubes lit up main cathode tube working. Had the unit power up for about 30 minutes with no issues. Not all functions were tested besides what you see in the photos. There is always a possibility of typo or an error that can potentially be made on our end without the intent doing so.
