content: Well good question, I note offer of 75+ by Fraser for entire logic probe kit in this thread herehttps://www.eevblog.com/forum/buysellwanted/wtb-hp-547a-current-tracer/So i guess priced in that region, but prepared to look at any offer. Ideally i'd like to pick up just the 547a tracer as i already managed to get the 546a pulser but if the tracer is offered as part of a bigger set i would be open to buying the whole set.Tks

content: OK. Recent ones on Ebay went for £67, two-thirds of the kit for £159 and the whole thing for <gasp> £252!I might have a spare available - I'll check and get back to you in a day or so if you like.

content: Thanks for the response and yes would appreciate any firm offer.As I said ideally WLTB just the current tracer (in good working order). To be honest don't think could stretch 250stg, max funds at the moment ~150stg... too many small mouths to feed here!Can pay via paypal or alternative & will cover P&P (to Dublin) as part of any deal.

content: There is none on Ebay the HP 547a have been selling from $100-$200 in the US. If someone brought that kit from Fraser for $100 they got a really good deal as one just sold for $500. I looked up mine, the comparitor kit with set of probes and logic clip $800

content: QuoteGosh, that is... a lot. I wonder if that's because any remaining unloved ones have found homes by now, although given their age you'd think that would have happened years ago. Maybe they have just got to 'vintage' status now

content: Shock is dead to rights there, some bat crazy prices for these going on ebay at the moment with an incomplete set going for 400stg in UK (no 547a included) and what seems to be a damaged set going in USA for 650USD (no probe tips, no case, no logic clip)...Luckily after a bit of searching I managed to source both the hp547a and a hp545a off another site for a couple of hundred bucks, so all sorted - thanks for your time lads.

content: What other instruments of this sort are there ?I have a 547 but don't often use it. It seems like something that could be further developed. Probably not too difficult to build a home-made one either. If it's hard to make something with a small enough size for the sensor, maybe a surface-mount hall IC or the head of an HDD could be used ?I know there's the i-prober, and I particularly liked Mike's modifications for audio and a spatial view of current density. The i-prober is fairly expensive but it's comparable with those ebay prices !https://www.eevblog.com/forum/blog/eevblog-296-aim-tti-i-prober-520-current-probe-review/https://youtu.be/_xvpLisMr7w?t=731

content: Apologies for the necro. I recently acquired a mostly-complete HP service kit, with the Logic Probe and the Pulser in the satchel. However, the Current Tracer is absent. I'm OCD enough to want to complete the set; is anyone here still willing to part with their 547 Current Tracer?
