hi guys i have a question for a replacement component cause i had hard time finding it, the component i am talking about is an audio output transformer, It consists of an 8 ohm coil and a 1000 ohm coil and it is like the one on Radio Shack website https://www.radioshack.com/product/index.jsp?productId=2103254&cp

i really want to find an alternative component to it and have the same effect on audio signal, i want to amplify it, so if anyone know another component that can replace it please inform me and the reason why i can't order it online is that i need it urgently and it takes time for shipment and i am in a big hurry.

thanks in advance.

compugeni,
I haven't checked lately, but Radio shack used to carry a line of 70V transformers. To get the impedance ratio you need, you would have to use the 5Watt tap. The closest you can get with a standard 70V transformer would be the 4 W tap. This would give you a 153:1 impedance ration, instead of the 125:1 impedance ratio you desire. Not exact, but maybe close enough.
Regards,
Kral

its very difficult to get audio transformer of this spec.i have been trying to get it but could not find it i tried to get it manusfactured but the performance was not good. than i shifted to the design.i hope you are using it at output stage of classB amplifier i changed the power amp from class B to class AB and got rid of audio transformer
