    I need an audio transformer for an old tube amp. I don't have the old one to look for numbers etc. So isn't it possible to find one that would work knowing the few details I do have on it? That would be that the output wattage is 6 watts, the impedance is 4,8, or15 ohms. There are three taps on each side and the physical size is about 2x2x2 inches. This is a Heathkit A6 mono amp from the 1950's. I've looked at all the places on the web and the Heathkit parts or whatever website which is more or less a dead end.
    Put another way what parameters of a circuit or a transformer determine your choice of transformer? Thank you for any help.

    The output audio transformer is used to match the output impedance of the final amplifier stage to the load (the loudspeaker).

    Is your output stage push-pull (two output tubes) or single ended (one output tube)?
