You could measure from the focus control as that is a convenient access point.
The next point should read +135 volts to chassis.It may be accessed at C148B positive connection.
The voltage at the C147C positive should read -60 volts to chassis and the can of C147 should read -120volts to chassis.

Ok I measured directly on the divider resistor, here are the readings from right to left:
1st term (under trans) 202v
2nd term 340v
3rd term 0
4th term 15
5th term 31
measured in dc scale, black to chassis
