I purchased a NOS (sealed) Hafler P3000 MOSFET amp that had never been used still sealed from 1999 and it played great for a week and and now one side/channel gets really HOT and a loud HUM. I have fans and used it gently for several days when I first opened the box and I really have not pushed it hard with efficient vintage Klipsch Cornwall speakers.
I worried about non use for 15 years and a cap failing etc but I got a great deal on it as it was going to be my back up for my analog system. I think Musical Concepts is one shop that works on Hafler but they are really expensive, anyone here work on a MOSFET amp? http://www.hafler.com/techsupport/pdf/MAN1461C_P1500_P3000_man.pdf
