Sorry mistyped I meant to say that I've had the SSP 800 for over 7 yrs not yes.

dear friends , tks for your comments ...right now i have found the main board damaged , and i`m trying to buy the components to replace ... i`ll notice if i have any success !
tks everyone
Mine developed an issue and was sent back to Classe via my dealer, it was repaired under warranty. The factory reset is always a good first try after the obligatory "reboot" via power switch in back by cord to resolve odd ball issues.
