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 tubes, and why it happens. See the bare minimum of component replacement to make the device work ag...

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 capacitors that the others don't see. This unit can also be used to "forecast" future possible capacitor...

More PCB files released, and I still have tons to go. Feel free to build and enjoy! Be aware that full mains AC is present on this device, use extreme caution when building this! If your unsure of working around this sort of thing (Mains AC) do not build this project. If you build this, you're doing so at your own risk.

They heard us all loud and clear (Tons of emails from me!) A personal apology as well. We're back!
New Reward Levels added to get me back up to my original numbers. Some will be temporary offered (once your in, your in.) I will have to put on a limit of how many I can take on, as I can only do so much.

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?

These units are really "the th...

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. (Self test function)

While I'm working on the next curve tracer video, here is the release of the Capacitor Foil Side Tester PCB files "for the first time." Many have asked for this over time, so here it is for my Patrons. This was featured on Hackaday quite some time back, but no files were released.

Congratulations, you're now building your own test gear!&n...

Below is an attachment in PDF format indicating the proper capacitor orientation for the H/K Citation 1. The replacement capacitors are all .1uF, and a 630 Volt rating will be fine for all "listed on the map sheet."

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 verify more components, and share my results with you.
