Good day I am really bew on this nice forum and I need some help. I got an used 520 Preamplifier and I think it shows a malfunction. On the first start it emits a noise (trough the speakers), like a hum, for 1 to 7 minutes, after that it stops. With successive tur on and off, the behavior is normal, there is not hum or noise. It seem that when the ambient temperature is lower, the noise last longer. In any case the noise is not so loud, but you can ear it at 1-2 meters from the speakers. I have tried changing cables, using current filters, earth connection, almost everything. Then I took the Pre and went to a friend´s home and connect the pre with its gear...We eared the ugly noise...Has someone experienced the same thing? Obviously the Pre it is not under warranty. Thanks for any comments.
