The oscitator coil 05985(3)has 3 set of windings.Inner tube/coil and outer tube/coil plus the one in trouble over the outer coil.The one in trouble you suggested for kathode circuit I trased and repaired/rewinded succesfully-was reading too high @100 ohms. 25 turns,38awg wire on stip of poly.scotch tape.Before did this surgery I noted this sceme on paper.Cleaned the base coil and lackered with polycoat spray.After rewinding it is reading 5.5 ohms.Riders wiring states 3.5 ohms.Is that ok?Btw: From Kathode of 36 tube to lug #1 via new coil,out on lug#2(clockwise counting) via 10k resistor bypas with 700 mmf-mica cap to ground.
Got to do more tracing on the other winding of same coil.Still bit puzling!?
Thank you so far!
