I recently tried an experiment with my amp. I substituted a NOS Mullard GZ34 for a 5U4GB. Where there was NO noise or hum with the 5U4GB, the GZ34 hums. I have two of them and substituted one GZ34 for the other GZ34. The hum decreased but did not go away. I Thought full wave rectifiers are interchangeable as long as the voltage differences are accounted for.
My problem is that while it hums, I like the sound of the GZ34. Any ideas what might be causing this?
