@tornfuté, see the attached book, SGZ is mentioned here.

"Brandt started the development of a small console in 1940. This unit contained the ‘Kino’ (motion-picture indicator) SGK, the twin amplifiers SGZ and power supply SGN."

@tornfuté, i think the next step would be to find this book:

http://www.navy-history.com/Einzelexemplare/D/Die_Sonaranlagen_der_deutschen_U-Boote.html

ps. can you make a good photo of your SGZ frontplate so i can recognize it when

i see it on some picture? Thanks.

Val i agree with you i had listed this book it’s availlable on amazon 

i just mind if Rossler decribe in details all the sonar types.

in your pdf i have find this , p83  sonar type 200 is using SGZ

i know submarine own a serie of 2x 12 microphone on the hull

and the twin amplifier is connected to amplifier  acoustic signals 

then it’s displayed on mirror indicator .

Will do picture later of sgz
