anyone own an amp where problems always seem to land? I have tossed "or my wife has sold" all my old amps that were mainly cheap diy stuff I put together. but back in the day caused me problems when the internet couldnt help. do amps still exist that cause you nightmares? just looking for some horror stories...I had a 1990's portable altoids amp that ruined a crosscountry flight by going dead and in the trash...
