content: Easiest way to get an idea of price is search ebay for sold items, look at the prices it sold for and then subtract ~20% that would be consumed by the seller fees. You can always adjust based on current market conditions and other factors.

content: Hi James,Thanks for the tip - it's pretty rare that these go up for auction.Most are sold as buy it now or best offer on ebay.There is a huge variation in the buy it now prices, from US$5k to $9kPerhaps the $5k price is about right in which case I should sell for $4k?Regards,- Guy

content: Well it's worth whatever somebody else will pay for it, but you might try asking $4500 with reasonable offers considered or something like that.

content: well no probes equal no value, sorry, but they are tca xxx and yes they are expensive, but they go with the scope.not having them and priced properly with all of them is a no show, totally wothless to mei'm in the needs of such scope, at least in the same series .... frankly put asking and giving ....even if the scope is clean, they came from an old era .... and like many of theses era, maintaing them is somethingand calibration costs are in the 1K$$ more or less sticker says due 2007 i think (image too small)that's a lot of time ..my 2 cents

content: Unfortunately this scope came without probes.The probes I have are here are 13GHz tri-mode that I purchased for another scope / project.Definitely overkill for this for this baby.Cal should only cost around $500 AFAIK, unless you take it back to Tektronix ;-)You are correct about the last cal, it was in 2007.- G.

content: LOL the cal on my scopes expired more than a decade ago, so what? It's not like the instruments have a tendency to drift.Probes certainly have an impact on the value of the scope when expensive probes are needed, so you'd have to look at examples of sold instruments that were sold without probes to determine a fair price. Ultimately in the end anything is worth whatever somebody else will pay for it.

content: Quote from: coromonadalix on March 06, 2023, 11:38:43 amFYI, the TDS7404 was originally sold with 4 x P6139a 500MHz passive probes. Finding one of those scope with 4 active probes and at a reasonable price would be really surprising.Nevermind that was the TDS7054. The 7404 came with 4 x SMA adapters.

content: P6139A probes are what I use on my TDS784, they're nice probes. You need proper active probes to make use of the full bandwidth of the scope, but I typically don't need that and passive probes are a better choice for general purpose use.

content: @Guy_Ellis would probably be easier to sell if you find some adapters (to sma or bnc).

content: Hi Paul,Just to be clear US$4500 including shipping to US or EU, with 2x adapters.I can do a better price for AU, NZ or SE Asia as the freight cost will be lower.Regards,- Guy.
