Philco 86 Pwr Trans
#6

It's definitely shot.  It looks like someone attempted to "repair" it before me and literally toasted the PT.  The good news is that I found a stripped down 86 chassis on eBay that still had the PT on it.  I took a chance and bought it for $30 and after I rewired the primary and CT leads it worked like a charm.  Reinstalling it will take a while but it looks like I'm back on business.
