Should repaired equipment be stated in the ad??

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

but I suggest disclosing full details of any repair or service in private emails after an initial inquiry has been made.

I can go along with that, but I did ask in a private email and was told " I have tried to list everything about these in the ad"
That statement turned out to be dishonest as I found out later on the Audiogon forum's.

So even disclosing that in private emails will only work if the person is honest. In my opinion, If they don't put it in the ad they probably wont tell you in a private email either. At least in my case they didn't.
