Re: GPO Tele 121
Many thanks Russell for the info, I looked all over the web but only found bad copies.
Now just a matter of locating two parts. Retired from BT 20 years ago after 32 years, Regards Graham M0AZJ |

Re: GPO Tele 121
I think my copy of 'Atkinson' has a 121 circuit diagram. I'll post it on here if it's any different to the 'N'-diagram.

Re: GPO Tele 121
Graham,
Attached is a PDF re: Tele 121 from my 1947 'Atkinson'. You might find it useful.
