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.

The 5Z3 may be sorted, please find a tube checker - and leave the tube in long enough to get warm or hot to the touch before testing!
If you are in the Vancouver, BC, (Canada) area we will have a tube tester and will verify if the tube is good or bad for no cost as long as you come in. If you send/mail us tubes to test then we charge for our time...

SHORTED, not 'sorted' - must proof-red!
