Most modern amps are DC coupled. That means the bias (and therefore the quiescent current) for the later power stages (those stages that do the work and get warm) is set in the earlier stages. The high gain of the earlier stages means a tiny change there can produce big changes in the way the later stages work. Those early stages are sensitive and more delicate so some damp and dust or dirt can cause far reaching damage. Time to consult a repair shop...
