My father just gifted me a set of Onkyo 25A's. They're a large set of floor-standing speakers that were produced in the early/mid 70's, but I can't seem to find anything on them other than one clip of an advertisement.Link
Apparently they were top-of-the-line and cost about $400 in 1974. Anyone have any idea where I can find info/reviews/schematics on this speaker?
The reason I'm looking is that the tweeter in one is not working (model no TW-301B). Is there any way to find a replacement part? If not, what should would be the best course of action? Sorry, I'm not to familiar with audio components, but thought this would be a good place to ask.
