Thanks Six, I am kind of leaning tword a bad tube as I did see a bright flash through the vent side when I turned it on and the fuses blew.


Now is it safe to remove tubes, I have no idea on working with high voltage and have no idea how to ensure all the capacitance is discharged.


I havent really been pushing the amp very hard so I am really surprized a tube blew, its only 2 months old. Should I just put the 572b tubes in it ?


Working on an amp is the one thing that scares the crap out of me.


Thanks for all the helpful hints..
