No factory warranty on the amp (purchased directly from AVA in 2017 as one of their certified second hand units). New tubes (JJs) and factory certification at that time. It, and the listed preamp, have been in my second “home theater” system. We are downsizing to a smaller townhome and I will only have room for one system. Based on serial number I think manufacture date was 09/11
Since I’ve owned them, probably only a couple hundred hours useage.
