Don,
More to previous post 5A3 at CRT board pin 3 & 4 go to pin 9 & 10 at
CRT and those are the filament pins as per print... Check that CRT board
there have been problems with them.. I still feel you could have a
compatibility problem with that transformer, but could be wrong. BTW how can
you test the tube if you feel the filaments are open?

Don,
Found a manual for a 9-1672/73... filament windings of fly are #5 #8
one goes thru RX3237 5W resistor no listing of value. to connector 3A5 pin
#3 #4 to CRT board 5A3.. and yes 24K sounds to low for a 35# tube.. print
says see HV chart but could not find a chart... Like I said I have had NO
LUCK with generic transformers on the 32" 35" Zenith.. Also pin #1 at 3A5
is the 215V supply to CRT board.. You may want to check the CRT board as
they have had lots of problems...
Hope this helps
Bob,
