Tube flash


Is it possible for a tube to flash, blow the fuse in the amp, and then test ok on a tube tester? Or is my tube tester broken?

Any insight would be most welcome.

Well lets see... the tubed flashed in the equipment. The tube was pulled and tested ok in the tester.
Put the tube back in the equipment, maybe flashes again but this time damages an electrical component or trace on a circuit board.
Yep maybe the tube was bad after all..... Hell of a way to find out, use the amp for a definitive test.

May not be the tube that caused the fuse to blow.... Might be though....
Thanks Newbee for pointing out about the yellow highlighting of the word "bad".... The yellow highlight is the nature of the beast apparently in the AA program when doing a search.
I entered "Bad EL34 Winged C tubes" so the word bad will be highlighted in all found posts.

And yes as you pointed out Jim does not say all EL34 Winged C tubes are bad.
