The numbers on the dial are backwards compared with what we're used to, but otherwise it's very similar to the UK variants, which have an almost standard 300-series chassis albeit modified to work in a wall-mounted case, see here: https://www.britishtelephones.com/ericsson/n1071.htm
The dial was a mess (seized clutch and broken return spring) but I've restored everything now and would like to use it at home.
However, there's a catch... this seems to be an instrument re-designed for the NZ telephone system. It has an extra changeover contact on the gravity switch and a separate earth connection. There's also an odd, asymmetrical leaf spring on the bell motor.
I've attached a photo of the paster in mine. You can see it's very similar indeed to the standard GPO 332: https://www.britishtelephones.com/gp...t322paster.jpg
So, to the big question... What do I need to do? Certainly, linking T2-T3 would be a start, connecting the line to the points marked A and B.
Two-wire working would be fine. And obviously, I realise that I'd need to do a bit of mental conversion when dialling!
Thanks, experts,
Nick.
EDIT: Mods, please delete the "party line" bit from the title  |
Used with 'multi-party' party lines which used code-ringing on Strowger exchanges in NZ.
Quite easy to mod to have an identical circuit to a GPO Tele 332 -
a) Remove the green wire that runs between T1 and Switchhook spring No 3
b) Move the brown wire from T3 to T1
c) Remove the Slate(grey) wire between Dial terminal Strip 2 and Switchhook No 4
d) Remove the Orange wire between T12 and Switchhook 7
e) Strap Dial Terminal strip 2 and 3
f) Strap T11 and 12.
Then your telephone is identical circuit to a Tele 332 except that Switchhook make contacts are No 5 and 6 rather than No 3 & 4 on the Tele 332. Line A wire goes to T1 and B wire to T9 as per Tele 332
Then just go ahead with converting a Tele 332 to three wire as per
Bob F's instructions -
Then the telephone is ready to go.
Note the NZ dials are identical to the UK ones except for the fingerplate.
