Well so I did bridge right pin R32 to Z5pin7, but this still doesn't give me 0v continuity on pin7.
What about pin12, pin7 is directly connected to pin12 but pin12 hasn't got ground, should it?
pin1 -> R37
pin3 -> 0v
pin6 -> Z3pin12
pin7 -> pin12
pin8 -> R38
pin9 -> 0v
pin10 -> R37
pin11 -> ?
pin12 -> ?
Have you looked at the schematic diagrams in the service manual (post #0)? Z5 is five transistors that form part of the Comparator and some of the Sawtooth to Pulse Converter, all part of the Clock Oscillator circuit on the first page of schematics, top right.
The Emitters of Z5A and Z5B are commoned together internally and share Pin 3.
Some of your connections listed are incorrect:
Pins 7 and 10 are connected to each other and to one end of R32. I would not expect that junction to be at 0V normally. Monitor it with a 'scope rather than a voltmeter.
Pins 2, 4 and 5 are connected to each other and to R35 and R36.
Pins 1 and 12 are connected to each other and to R37.
Pins 3 and 13 are connected to 0V.
Pin 9 is connected to R31 and Z4 Pin 5.
Pin 11 is connected to +15V.
Pin 8 is connected to R33 and to the Base of Q8.
Pin 6 is connected to R24, R3, Z3 Pin 10 and the Collector of Q7.
Pin 14 is connected to C8, R38 and Z3 Pin 6.
