Any problem with Cary SLI-80 INTEGRATED AMPLIFIER

I read somewhere here but can not find it anymore.  Someone stated that he had problem with the tube with his SLI-80.  Anyone having same problem.  I was thinking if I am going to buy one, should I buy brand new or used.  If I buy new one and time to resale it then I will lose maybe half of the money but if I buy used then I not going lose much money.  If this one would last for long time with out any problem then maybe worth it to buy used.  Comment please.
