Customer brings me a Ceriatone Dumble clone he has never powered up, and a pair of TungSol 7581A to install and bias. This is my first encounter with this tube. I'm wondering where to bias them. The datasheet says it is a 35 watt plate dissapation "direct replacement for 6L6GC, but features additional controlled zero bias characteristics and a low loss base."
What does that even mean?
