Hi,
Afraid not - the old Freshwater site now at http://www.britishtelephones.com
(probably of interest to several here!) is the usual resource, but it doesn't
seem to have a schematic for the DTMF Trimphone :(
You could try uk.telecom - there are still a few old-timers there and someone
might know. I suspect that the data was never released as those phones weren't
supposed to be field repairable at that level :(

The one next to me here is a rotary (1967 I
think, a GPO 706) - when
I get time it'll be replaced by my 1940's one (a 162)....
Just as an aside, you wouldn't happen to know where I could find a
schematic, or service manual, for a 1970's "Trimphone" (the DTMF model
rather than the rotary dial model).
