Many thanks for the link, Dave! 

I need to build one of these. Unhitching every capacitor to test them is such a time sink on rigs like these. I have an unmolested HQ-120 that I want to restore and this tool would be perfect for that project.

Yeah, that video is the "build" video.

Hi:


Mr Carlson's Lab also has a separate video on his "Super Probe" that's over an hour long.

This video is very interesting indeed. A fellow built of high sensitivity, High amplification RF and audio probe. Put a little B plus on your B+ bus, go around capacitors and resistors and this thing is sensitive enough to pick up the miniature lightning inside a leaky cap even when it's too small to be heard in your speaker  Pretty cool. I intend to build one, although I probably will try to use IC amplifiers after a Hi-Z fet front end, rather than discrete comonents but we'll see. Has a schematic in the video and more information under the video.  I'd like to try it with B+ on the bus but the filaments turned off. You should still get the lightning.
