5th term 31
measured in dc scale, black to chassis

I assume that the DC voltages on the 4th and 5th terminals are negative with respect to chassis?
The second terminal which is supposed to be +135 volt measures 340 volts: is that correct? I assume you have changed the electrolytics. If the 135 volt line is so high, it may be that the wiring may be incorrect. Please check the wiring closely around these points.
In addition, the -15 volts and -31 volts show the correct division ratio of about 2 to 1. (It should be -60v and -120v). This would imply that the other end of the divider is open or high resistance. Otherwise something is pulling down the -120v.
Please check the wiring.
