Hello,

Sorry to hear about your problem--especially on a holiday weekend. According to your manual, the fuse closest to the IEC plug is the output stage B+. This fuse is a 3 to 5 amp slow blow fuse not a .500. I would replace with what is in there now--which seems to be a 5 amp slow blow.

The cause most likely if I were to guess--is that you have had one or more
output tubes to arc over. This is not such a big deal. I would check the DC offset and if it's difficult to zero out on your meter--then you may have one or more output tubes go south. Just replace the tubes if you have some and if not then do a statistical swap with the tubes that are in there now til you get the DC offset to settle down.
