I have an old Marantz PM57 amp which must be about twelve years old now. When I first turn it on the sound I get through my speakers is crackly and fuzzy. After about ten minutes this disapears and the sound is fine. I have changed both speakers and speaker cable and the issue has continued hence why I figure the problem is with the amp. Before I buy a new amp does anyone know of anything specific that might be causing this and/or could it be easily fixed or is it more likely that something is amiss and I need to replace my amp?
