    Does anyone have the specs on a Majestic 8105 output transformer?

    I noticed that one of the output tubes was running hotter than the other. Swapping tubes didn’t change the location of the hotter tube. Obviously something was wrong with the bias circuit. More testing revealed one side of the output transformer is caput. The limited info on I received from CVR didn’t provide details on this transformer. Does anyone else have info on this radio type?

    I believe the 41M is nearly similar to the 6K6 pentode. In push pull configuration, you need about a primary impedance of 14k plate to plate, center tapped. I don’t have the schematic to see it. Is the speaker 8 ohms?
