Depends if you are referring to the amp as a whole. Until the OP gets back to answer some questions all other suggestions are meaningless.TrevC said:Agreed. Whatever the problem is it's in the amplifier.keeper of the quays said:I can send the op my spare phono stage..they can then try it to see? If it makes no difference? Amp is faulty! If it makes a difference then phono stage is faulty! Tape it off..never use it again..life is as simple as you want to make it?
