On the primary of the power transformer from the ct to each end should see 6vdc with the vibrator running. If not contacts are bad, you may be able to cut it open and file or sand them clean to make them work.
Check the resistance on the pri and sec of the pt may by open.

ok on the one side of the transformer ( secondary? ) that goes to the OZ4 across pins 3&5 I get 25vac 12.4vac to chassis on each side.
Across the small pins of the vibrator I get nothing (.4mv) Across the 2 large pins I get 3vac
From the center tap( lower large pin ) and either small pin I get 3vac.
Sounds like the vibrator is bad?
