Some older gear might be in need of some refurbishment, such as new caps, re-bias etc.. If the unit in question comes with detailed documentation of the "checkup", even if it was for a repair, I'd consider it a plus.
Manufacturer checkups
This question is in reference to an older preamp I recently purchased with which I have had no prior experience. Some classifieds state the item was recently check out by the manufacturer and given a "clean bill of health". With an older item that has no functional or visual problems and no obvious sonic deficits, is getting that item checked out worth while?
Thanks
