I was thinking tubes, bought a new set, it worked fine for an entire 3 hour practice, then blew both fuses (.500a ht and 4a main). It appears the GZ34 rectifier tube is bad, so I put in a good 5u4 I had, and the amp worked. I bought another GZ34, played it, all was fine, turned on again and the HT fuse blows. Replaced the HT fuse, then turned on, and saw the brand new rectifer arc and both fuses blew.
This just killed my new rectifier tube. Bad PT? What can I check next?
