I agree with sfar, tube devices will eventually have problems with the tubes, it's part of the "experience" of tubes.
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.
