SET amps run at 100% duty cycle all the time. I wonder how fast that wears out tubes compared to a push/pull amp?
__________\\\\\\markpao: Can you please provide the name of the tube tester you have. Do you know if it will test 805, 300B, 6SN7 and 6SL7?
__________\\\\\\tvad: for 300b replacement tubes, please look at the Psvane Acme. They made a nice improvement in my Line Magnetic (along with the other rolled tubes on it)
