NTP M920 vu meters infos

[EKADEK]

hi  there  folks.  ive just received a pair of  NTP 920  VU  meters. 
from denmark.
all lovely. 
seems to me  - after experimenting  -  like i need to build a special amplifier for to drive them.
any ideas and infos would be truly appreciated.

Lovely  ...  I would say a limiter amp  ..  could be TGee or could be Nvee  .. at least thats how I see it

PM me your e-mail if you want full documentation of the M920 meter (also called 177-600, depending on the enclosure). I scanned it last year. There's some calibration instructions in there that you might need.

PRR is right: it's a complete unit, no external log amplifier is needed.


Edit: oops, turns out I already shared it, although heavily compressed.
