This is an "almost" real time repair (1 Hour) of a large power supply and tube amplifier used on a set. This is an example of how fast repairs need to be accomplished in the field to get things moving again. Here you will learn fast component recognition, transformer wire colors, discoloration in...

This ranks up there with the "Carlson Super Probe." This tester will test capacitors for leakage without the "High Voltage" used in all the others! This is a much safer alternative, and if that's not good enough..... It's even more sensitive than normal HV leakage testers, It picks up faulty capa...

Here is the build process for the capacitor discharge device, with circuit explanation. See how it performs as I discharge a large capacitor. Do you think we should design a "smart discharger" together? (see the video for more details) Let me know your thoughts in the comments below.

Use these devices to protect your sensitive test equipment, here they are displayed on the Curve Tracer project. See what happens when I feed 600 Volts DC into the curve tracer's front end! (Protection device installed!)

Here are all the files (see attachments below) to build the "Super Probe." This extremely sensitive, non contact probe may be one of the most useful pieces of test gear on your bench.

Find faulty components with no schematic's, no power applied to the circuit, and little to no knowledge about the circuit under test. Sounds too good to be true right? Why industry is so secretive about these tracers will be quite apparent in this video. Here is the Signature Tracer 2017-12-01 17:08:34 +0000 UTC View Post
In this video, I display the steps to correctly clean VR's, switches and circuit boards. A safe CRT removal procedure is also included. The alignment procedure for this scope is displayed in detail, and I use the existing oscilloscope functions to test it's own internal curve tracer circuit board...

I have completed some component testing, and found these parts to be "really good." I will be using these parts in many future builds. If you're following along with my design,restoration and repair videos, it would be beneficial to have the same components. As these videos progress, I will verif...
