Do you own gear from defunct brands?

Think once something is out of warranty, does it even matter? You can't really get service manuals anymore, most things are now surface mount and IC based. Almost no one can fix them anymore. 

Most of my system is vintage Hitachi, with vintage Klipsch speakers, most of them have been restored in the last couple years, hopefully they outlast me.

Does anybody except myself still use a Lexicon DC-1 ? I just use it for 2 channel listening but I have found it to be pure without any deformation. I have had it about 30 years and I paid a very average price and the only drawback that I know exists, is that it is subject to failure from power surges. I used to live at the beach and the hurricane power surges got me a couple of times but I got that under control now. Just wondered if anyone else still uses this old equipment.

Hardly defunct, but no more new production, so yeah.
