For me it depends on the circumstance. If the item was dropped or mishandled and needed to be repaired I would want to know that. It would also matter to me who performed the repair. If someone had their buddy who thinks he’s handy with a soldering iron fix it to try and save a buck or two vs sending it back to the manufacturer, I would certainly want that disclosed. But that is not what happened.
Personally, I always disclose if an item has been in for service while i’ve owned it as well as who did the repair. However, if I purchased something and later found out it had been sent to the factory for a repair I doubt it would bother me that much. In fact as others have said I would probably feel much better that it had been in for the repair instead of having to deal with it on my dime later on down the road.
minorl makes a very good point about tire kickers and I get a sense that is the case here. Had you been happy with the preamp I find it hard to believe the repair would be an issue here.
