This amp i made them exchange brand new 2 years ago because there was a recall on them and they said that this model had been fixed, so they gave me a new one. It has been working fine for 2 years so im gonna go with a tube problem for now... :confused: . Its a traynor cv80, sorry i got mixed up..what i wished to say was it has a feature where it is "Autobalancing bias supply means no need for matched pairs of output tubes or bias adjustments".

Anyway i can get around not bring it to a tech...im sooo poor.
