I’m looking for opinions on whether to dive in and build Paul’s super probe or just buy an existing Heathkit, B&K, Eico…Ect. Has anyone built it and what kind of cost/added benefit it has over buying a signal tracer.  Thanks

Hi, I am not sure if you are referring to the Superprobe project or you meant to say Ultraprobe as they are 2 separate projects even though they do they aim at the exact same functionality? However, the Ultraprobe is vastly superior and newer than the much older Superprobe project and I can assure you that if you build the new Ultraprobe it sensitivity far exceeds any Heathkit or B&K, Eico etc. equipment you would buy  and a great advantage is that it works on normal batteries or even rechargeable (should you prefer) and it is small (not much space required on your bench and it goes without saying (no mains power required) In fact the probe is so sensitive you could find bearing noise in cars or any other hidden mechanical problem (IE: unwanted vibrations etc) that is otherwise hard to detect. Cost ways…well, it all depends on what you already have in your junk box/spare parts + look / examine the BOM yourself and then decide weather you are good at making your own boards (the SMD style ones) or you would rather not get involved. Anyways the components are usual (some of them specific to this project) but, nothing super special and/or overly expensive. Again…it is entirely up to you. This is my own opinion and it is not to be taken as a definitive advice and yes I have successfully built both projects as well and they work like a dream. Whatever the decision…good luck.

HA!  Yes the latest and greatest Ultra Probe. He is always upgrading/revising his builds, hard to keep track for a noob like me.  Thank you so much for your response and input.  I’ll be building my single ended 807 amp this fall/winter and have built a couple of Paul’s tools.  It seems to me having a signal tracer would be the next logical tool to build regarding the amp.  I do love finding and repairing older Heathkit or sim. equipment but at some point when does repairing and just building new cost and effort converge.?  I appreciate this input and will reference this again when that project.!  Thanks Gale

@markboston42 Hi, if you are a Patreon member then head over to Patreon and search that official, list of videos for the videos 174 and all the way to 182.  They show the progress and variants to build for the probe head unit (either thru hole or SMD construction).  However, there is no thru hole version of the base/de-modulator unit er…. but you’ll understand far better what I’m saying after watching those videos. For the specs, schematic box drill-out template and B.O.M. you need to request those manually via the private messaging system directly to Mr.Carson and you should get them in a few days directly to your email (the one you are registered with on your Patreon account. However, keep in mind that you need to write down the specific video number you need the documentation for otherwise he wont know what you actually asked for and you wouldn’t get them. Also keep in mind that the whole Ultra-Probe project is split in 2 sections  1: is the so called base unit or the amplifier/de-modulator box  and 2: the probe head unit. So, you gonna have to make sure that you ask for the documentation of both (providing specific video numbers of that list. Good luck.
