UK Phone Voice Scrambler No. 6AA → ← No. 6A
|
Telephone scrambler · 1940-1942
- this page is a stub
|
|
Introduced in September 1940, this version was nearly identical
to the 6A, but was suitable for the 200-250V AC or DC mains
and had therefore a live voltage-carrying chassis (like the No. 6).
|
This version was intended for use in areas that still had a Direct
Current (DC) mains power network, with the ability to run from
Alternating Current (AC), once the local mains network
had been converted.
At present, no image of this version is available.
