Non responsive magic eye is usually caused by a burned out 1 meg resistor between the plate and the target. I would not call it a simple fix as you need to open up the eye tube socket housing to get at it in most cases. I think an RCA 15K is a set well worth keeping even if it isn't a Philco, the RCAs from that era are basically communications sets in a nice wooden cabinet.
