FYI - from looking at the schematic, R124 is used as a current limiting
resistor and supplies current to both I101 and I102 (dial lamps) from the
6.3 volt winding on T801 (power supply chassis).  If R124 is open, both I101
and I102 should not be working.  Possibly one of the lights developed an
internal short which forced R124 to act like a fuse and burn open.  I would
check and/or replace the dial lamps prior to replacing R124.  The dial lamps
are both type #328 bulbs, by the way.  Just some thoughts.

Good luck.

Sorry, that should read "resistor R124" ,  Richard
