Early 1990' s vintage solid state mono cassette recorder with SofTouch logic solenoid control.
It can be used with up to 6 headphones for group listening such as in schools/colleges.
I purchased very recently and it was sold as "fully working".
Mechanically everything works well, but there is no playback sound when playing tapes, the same on internal loudspeaker, external loudspeaker, line out and headphones.
There is hiss sound but not tape hiss, because the hiss stays the same when tape playing back is paused or if no tape is present when play is selected.
The volume of the hiss can be varied with the volume control, but the level of the hiss can be different for the same volume setting, e.g. with volume set to mid position the hiss may be quite loud or quite quiet at different times.
Apart from the User instructions was not able to locate any other documentation so posted a documentation request here -
