Help repairing Akai AM-M939

Check D4b and D5b zener diodes.I'm guessing they are 11-12 volt zeners
HZ11LC3
11.4 v - 11.9v 500mw to be exact.

Hmm, the voltage on one side is 1.2v and the other is close to 0v. This is for both sets of d4 and d5's. + and - taken into account.
 
Hmm, ive also checked trs 8 and 9 on both side. Some of the pins are half the voltage of the other side. Should this be correct?
 
Just in case....
