Recognize this set?

[ctc17]

What dave said on the tuner, but I usually slide the cracked gear off, clean it up really good and jb weld it back on the ribbed shaft. Every zenith I own has that gear cracked.

How was the cutoff on that crt? Were you able to get up to high in the red? What kind of emission do you get at 5 volts? (i have the same crt tester)
That red and green color bleeding can be caused by a semi week crt.
