Build a “Carlson Super Probe” and make your electronic troubleshooting easier. Locate noisy parts fast! This is a “non-contact” style probe that listens to your circuits from a distance. Great for Audio and RF applications alike. Schematics and full description are in the video. In the end, Paul will demonstrate Continue reading Troubleshoot Electronics FAST with a Super Probe
How to design, build and install a buffer circuit into a receiver, so you can give it a digital display. Learn how to locate the oscillator circuit in a receiver without a schematic, using a new, and older vacuum tube oscilloscope. Lot’s of other “bonus” repair information as well. See Continue reading Design and Build a Buffer Circuit, Tube and Transistor
Watch the build process of a Nixie Tube digital display for older receivers. See the design of a scratch built circuit board, and the thought process involved in component placement and population. This is the final part of this Nixie tube series. For the earlier parts of the series, click Continue reading Nixie Tube Digital Display for Receivers
Join Paul in the Lab for a sneak peak at some future projects. Watch the teardown with a description of how the device works, follow along through the in-depth schematic explanation.
Build a neat little “flashy” circuit to get peoples attention. This worked very well! Schematic included with description.
How to build a programmable frequency counter for your favorite receiver, with “off the shelf parts!” Give that old radio receiver a digital NIXIE tube display. No special programming required. Join Paul in the Lab as he thoroughly explains how this, and many other frequency counters work.
In this video, Paul explains how to make a simple crystal oscillator, buffer and frequency division chain. This can be used for many different applications, IE: frequency standards, clocks, frequency counters and more. This is the second video in a series on how to build a Nixie tube frequency counter. Continue reading The Crystal Oscillator and Frequency Division
Join Paul in the lab as he explains how a Nixie tube works. This is the first video in this series on how to build a Nixie tube frequency counter from scratch.

Join Paul in the Lab as he repairs and improves a Precision Apparatus Company E-200-C series signal generator. Learn how to adapt a frequency counter to any older signal generator. Follow along as Paul describes how this signal generator works, and explains the factory schematic in detail. “More troubleshooting adventures.”
More electronic troubleshooting adventures! Join Paul in the Lab as he explains “in great detail” the circuitry inside a Heathkit T-3 signal tracer. Then Paul will discover and fix some design flaws. See how the Watt meter (eye tube) and noise tracer functions work.
