Turned on the ole maz 18 nr studio....no sound....just a buzz...jumped behind to find one of the power tubes not glowing at all...Fully expected red plating...
I tapped and slightly moved to see if connection?...still nothing...turned amp off...in goes the fresh set...turned on still buzzed...left tube no glow...stood in front of amp and it slowly came back to normal...(head scratcher)...Vol/tone/glow,all there...no buzz...weird.
In all my years with tubes...that's a first for me....

That's a head scratcher for sure, Dave. The only tube not glowing was the left output tube? I had something similar in an old Fender Champ II amp that had a bad socket on one of the output tubes. One of the heater connections had a bad connection in the socket. I'd check for good solder joints on the socket and make sure it's clean and tensioned properly.
