Yep. Fuses don't blow for no reason at all. Something is causing too much current draw - a.k.a. - bad tube somewhere. Did you notice if any of the tubes had plates glowing orange/red? I had some 6L6's and 300B's do that, but it didn't phase the amps one bit luckily.

The Tung Sol look better built but too bad they are rattling. Plus when the psvane were working I really enjoyed the sound.
I guess I'll have fun with some tube rolling. I already have a pair of 12AT7W coming my way  |
I had a pair of 5U4's that rattled in an old amp that I overhauled for one of my brothers. I replaced them with some RCA 5U4 GT's (used narrower, taller plates) and the rattle went away.

I had some EH 6CA7's for an old Consonance M-100 SE I had years ago. They sounded better than any of the EL34's and KT88's I tried regardless of being new or NOS.
On a side note, I've always felt that if you're going to own tube gear, it would be a good idea to invest in a decent solid state tube tester. I have one, though no tube gear now. Go figure. LOL
