Should repaired equipment be stated in the ad??

hi Kijanki, that's not what I said. If you read statement once more - I said

if a component was recently serviced by the manufacturer or reputable tech, it may indeed have higher value (eg, an older amplifier newly recap'd) than one that is original/never serviced.

read that it MAY have, not DOES have

So to answer your question, I would pay more for a unit that has been repaired, than for one that is broken. And, I *may* pay more for one that has been recently serviced (ie checked out, biased, etc) by the manufacturer than for one that has not been checked out in years by a qualified tech, especially if the alternative units available are in unknown, unverified condition. Example: a few years ago I did indeed pay slightly better than market price for a Bedini 100.100 power amp that had been serviced and recapped by Bedini 2 years previous. This is a 1987 vintage amp. In this case the seller did advertise the service. Likewise I paid more for my Electron Kinetics Eagle 2C amp than I did for my Eagle 2A - the difference between them being that the 2C had undergone a refurbish/upgrade. I paid more than 2 times as much for it, and would do it again.

So, as I said, I think it depends on the equipment.

I believe that is not so important what I think but rather what possible buyer might think. I don't want anybody to feel bad after purchasing things from me, so I would reveal what I know.

If I go by what I think then we enter dangerous territory - one might sell house that was rebuilt after big fire without disclosing it because it has, in his opinion, even greater value.

It's always best to be honest about repairs.
