Mike, try Gary Schneider at Play Things of Past. I think thats a common failure because my driver transformer also had an open primary and my spare chassis has an ill fitting replacement. But PTOP solved my problem with an exact used Philco x'former. My 38-116 is very sensitive and selective; only problem left is poor oscillation at lo end of BC band. Pulling the RF subchassis is interesting but performance of the radio justifies the effort. Good luck.
