Esteemed colleagues,
Could some member explain the jack inputs (2) on the rear chassis, immediately below the loudspeaker L ein-aus switch, which are designated with the letter T.
From the underside of the chassis there is a 50uF at 50 WVDC elko which connects to one of the 2 "T" terminals?
I understand from the historical pages" of the Museum of Sound Recording that a gentleman named Herr Kurt Stille was instrumental in patenting a "wire audio recorder" - the Telegraphone; and he also developed the Textophon (a wire dictation machine) in the early 1930s. I apologize if I have used inappropraite terminolgy for the instruments.
In early 1934 I believe the manufacturing firm C Lorenz (aided by radio engineer Semi Begun), had developed a "tape-type" recorder.
Is it possible that some of the Seibt Roland 5 series radios had the capability to "play back" the output signals from the early Textophon devices or the earliest AEG recorder/players?
Respectfully,
Robert

Gentlemen,
I believe there are still some final corrections to the Roland 5 series according to the information provided by Herr Birkner. There is possibly another configuration which may be identified as a Roland 5L Spezial - with minor circuit changes.
