Won this from an auction. Old theater that was originally a neighborhood family theater that devolved into an adult theater. The Foster Theater from the south side of Youngstown Ohio. A little cleaning, sanding and sealing, fresh wire and some power and it sounds great, mono of course.
Thank you Jond and cymbop. It really fills the whole house with sound, very clear. I added an SVS streaming source so my wife and I can play whatever we want from any room.
