that would lose conductivity after 3 minutes and you could rap on the tube to make it come back.I resoldered the tube pins and that didn't help so a year later I got that same tube back out and set it in my heath TT-1 tester and left it on for like 6 hours. I then put the tube in the citation 2 and biased it and have run the tube for 2 weeks and all seems well.
If the power supply waveform isn't pretty,neither is the sound in most cases.
