    Anyone know what set these spares go to?Interesting in that the
tubes are secured in sockets on an oddly shaped chassis.

  I think the chassis was shaped to fit a cube metal box.  What I want
  to know are 2 things:  Who marks an electrolytic capacitor EF 50, and
  where is the 6H6?

The EF50 is a TUBE, bnot a capacitor. The 6H6 sits right next to the
chassis, between the other tubes, and is hard to see.  virtually
