An amp like that is basically two sections, the preamp (before the volume control) and the power amp. If there is a patch loop or a "line out", check those for noise. Certainly not the transformer. Maybe the filter section of the power supply. Or the final output section. -- Philip _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
