Damon:  Thanks for the reply....please note, the primary winding is OPEN.  
Values I gave you are from SAMS.  I don't know the voltage on the secondary 
winding as it is not marked on the schematic.  The voltage from the secondary 
winding goes into a full wave rectifier to supply 27V D.C. for the sound.  Age 
of set - 15 yrs. old.  Good pic, beautiful cabinet.  Customer wants it fixed.  
Thanks for any further insight.    Kenny

  Doesnt' sound open to me.....28 ohms and 2ndary is 0.9......doesn't stepping
  down 110 V to what.....5V take about 22 times more windings than the 2ndary?
  I'm sure the 2ndary windings have to be a larger wire, since it's higher
  current on the 2ndary-less ohms.
  Now, do you think working on a CTC 130 chassis is a good thing to do????
  It's what, 2 years old? or 20?

  > RCA Model GMR868PR, chassis CTC130B - Need standby transformer RCA part
  #2863308-2  (according to SAMS 2622).  Primary reading 28.6 ohms, secondary
  reading .9 ohms.  Primary is open.  NLA.  Where could I purchase one?  Has
  iron core.  Surely there must be a sub.   TIA   Kenny
