Should repaired equipment be stated in the ad??

IMO, if a component was repaired/serviced by the manufacturer, and if the component is working properly and is up to spec, then there's no need to mention the repair/service in the ad. However, I'd answer any questions a prospective buyer might have about the component's service history.

If a component was serviced by a third party technician, then I think mentioning it might be a good policy.

I asked a seller recently is there was anything I should know about on a item he was selling and his response was " I have tried to list everything about these in the ad"

When I was searching the forums I saw a thread he started asking how to get this particular item fix and who could fix it " Long story, but I fried the upper mid left channel on my pair " stupid error " occurred.

I think this should have been in his ad,if not he should have at least disclosed this to me when I emailed and asked "is there was anything I should now about"

Just my opinion that's why I am curious what others think.
Thanks

Btstrg, your expectations seem reasonable to me.

Buying something that is still supported by the manufacturer seems a sensible precaution when buying high priced second hand audio items, IMHO.

Otherwise, I'd suggest to go for "bargains" only and accept that there is a high degree of risk - especially as audio users damage things quite often (a blown tweeter, a fried amp or a bent stylus being par for the course for anyone serious at this hobby...in fact most loud house parties will usually blow a domestic speaker, as they just aren't up to that kind of abuse)

Maybe we need something like Vehix.com where all repair shops report repairs done. Just put in make, model number and serial number and you get a complete fictional, fabricated reassuring history. Or you get a dirty laundry list of replaced resistors and caps and tubes and face plates.

I just got my vintage KT 917 tuner back from Stereo Surgeons complete with before and after specifications and a professional evaluation. If I were to offer it for sale, I would not attempt to conceal this info. In fact, I would consider it a selling point.
