Thanks Kindly for the response.

However the original speaker is totally destroyed.

I am unsure of the terminology, But the black transformer that was attached to the speaker, I believe one side of it is open. One side measures bang on 450 ohms, the other side seems open.

So all i have to deal with is the speaker thats on its way from ebay.

Can this push pull unit be used? The coil is only 100 ohms more from 450 to 550?

Cheers
