GPO 772 Trimphone Trouble

[maxmix]

Hi Guys,

Just finished working on my latest GPO 772 Trimphone, plugged it in, and nothing, it's dead as a dodo!!

It's wired thus -

Dial

Orange T8
Blue T2
Brown T3
Grey T1
Pink T10

Line

Red T1
White T8
Green T2
Blue T3

Handset

White T19
Green T15
Red T8
Blue T6

Straps

5-6-7
16-17-18-19 (These straps were as it came, which I assume was when it worked)

I know I'm missing the regulator (the Blue One, No.7?) But would this stop the phone working, without the regulator?

Any ideas? Have I mixed the wiring up??

I'm so frustrated, so much so that I can't tell you how much!!

Are you sure it's not 712 or 722? The 772 is a pushbutton phone based on the 746 platform...

Anyway, the wiring diagrams for the 712 and 722 can be found here:

712 and 722...

The 712 being the trial model of the Trimphone...

What is at the bottom of your post? I see 2 red "X"'s??
Is that supposed to be pictures?
Once agin ALL pictures need tp be put on the forum not linked to an outside site.
Thanks!

The dial is 712-styled (with the letters as well as numbers printed) but the board is standard 722. Weird. If I'm wrong, someone correct me.
