Good day. I am on the Glow Test portion of my build and the 12AU7 is glowing but the 6080 is not. The green wire is getting the 6.6V at each contact point. This is my first time working on a tube amp so am a bit new to troubleshooting a tube. My instinct is that the 6080 is bad or the contact points are not being made correctly between the tube and the octal socket. Any advice would be appreciated!
 
You might also pull the 6080 tube out of the socket and measure the resistance across pins 7 and 8 of the tube. Should read very low, just a few ohms. If that reading is in the right range the tube's heater is good.
 
Blimey you are right. I was really focusing on the directions as well. Just fixed it and the problem is solved. Thank you for your quick reply and help!
