Is the K38 speaker oval or square? I ask because I'm finding numerous 7 5/8" Philco speakers at PTOTP that have 1.2K field coils but many have no mention as to the shape. Since I'm not finding a K38 type I thought I can use any 7 5/8" speaker with the 1.2K field in this radio. I do have the proper output transformer.
