Should repaired equipment be stated in the ad??

Tvad
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.

Btstrg, as I stated earlier, you're expectations were reasonable, and you were hosed.

I cant believe so many dont think it matters if a unit has had a major repair......do you feel the same about a car?

Well said Chadnliz .

Like I pointed out above, there is not necessarily a negative stigma attached to service history. Vintage equipment needs caps replaced, tuners need re-alignment, old tube gear often requires cleaning of oxidation and can benefit from new wire.
Do you consider these to be repairs or maintenance? And what about mods? I see many ads crowing about mods having been done.
If it was factory R&R what is the problem? Items that didn't get caught by QC the first time through are returned to the factory for individual attention upon failure. These, I suspect, leave the factory better than new having received individual scrutiny.

Why so anal everybody? I buy used stuff aware that it is as likely to fail as new gear. The difference is that I bought it for hundreds or even thousands less than the original price. That leaves a lot of room for repair dollars in the unlikely event that they are needed.

Another point I might make is that most sellers on this site are overly concerned about their reputation and will bend over backwards to accommodate an unhappy buyer. As in any other area of transaction, you will find a degree of risk, but it seems that many of you are over-reacting to a problem you haven't even experienced.

Remember that you are doing this for fun. You have enough other things to worry about, don't you?
