DELTAPHONE Technical Manual |
The Deltaphone Technical Manual gives valuable information
about the Trimphones which were manufactured by STC. Only a
cross-section of information will be published on these
pages...
This particular handbook (STAA 66) details the Mark VI
Deltaphone which was given the STC reference of 66-LAU-67.
This version retained the same basic shape as the previous
series, but incorporated a number of circuit improvements.
