(No affiliation with Mr Carlson's Lab) As with our previous version of the SuperProbe, this SuperProbe2 conforms to the original Carlson circuit design, implementing a versatile non-contact very high gain electronic probe for investigating just about any kind of electrical signal from audio to RF. The design is well proven and constructed by many DIYers.

Anyone interested in building the probe should first review:

Carlson's YouTube video @ https://www.youtube.com/watch?v=uVkJqqZroN0 Yannick99 @ https://www.instructables.com/Carlsons-Super-Probe/ A thru-hole Design: https://stufinnis.co.uk/superprobe.html An EEVBlog Thread: https://www.eevblog.com/forum/oshw/paul-carlsons-super-probe/ Web search for many other reviews and assembly hints.

Here is a great UT video of Carlson using the SuperProbe to locate a noisy component inside a complex transceiver. He makes it seem so easy, and with the SuperProbe it is! https://www.youtube.com/watch?v=uiK1BD7HILo The PCBs This kit includes only the main PCBs with NO PARTS. There are many components needed to construct a complete probe and amplifier. While there are a few through-hole & panel mounted components, all of the remaining parts are 0805/1206/SOT23 SMD parts. Soldering such components requires specific equipment, soldering tools, solder, tweezers, optics, skill and patience. We will provide the same instructions that come with our complete parts kit, but you are responsible for sourcing everything. Schematic details are included and are identical to the original design. You have the option to construct the PCBs exactly as Carlson specified, or implement the improvements we discuss in the instructions. These PCBs REQUIRE ASSEMBLY. The Assembly While there are a few through-hole & panel mounted components, all of the remaining parts are 0805/1206/SOT23 SMD parts. Soldering such components requires specific equipment, soldering tools, solder, tweezers, optics, skill and patience. Follow the included instructions in detail. Schematic details are included and are identical to the original design.

Some of the listing photos show a particular implementation in a very compact package. Such compactness is not necessary, but demonstrates what can be achieved. Photos may include components not on the bill-of-material, and are included as suggestions for completing the probe.
