Audio Transformer Specs

[chaoseverlasting]

I need to replace an Audio transformer, EI-19 Output Transformer. What should I replace it with? I can't find the primary to secondary ratio, or the voltage ratings. Is there something special about audio transformers compared to step up/down transformers used in AC to DC converters? If so, what do I need to know to replace it?

What type of equipment is this in? An audio output transformer just about always is driving a speaker. An amplifier? If so, how many watts?

Any chance you can rebuild it?

From Google it looks like a EI-19 audio transformer just specifies the bobbin or coil size. What else do you know about it, or the circuit in which it is being used?
