[Jukebox-list] 780 blows fuse

Sorry I’m late getting back.  The box blows amp fuse when record comes up.  Was suggested to pull the 5Z3 and see if it still happens.  No, the fuse doesn’t blow when the tube is out of the amp.  Where should I go from here or what test might I perform to identify the issue? The amp has new caps from 3 years ago.Has worked with no issues until recently.  Thanks.
