Oldie, but great fun.
Service & repairs Vingtor & Stentofon.
We don't have any VAxxx boards for sale, but we can repair most of them.
Relay control board VA-117C , Zenitel / Stento / Vingtor Marine VMP-systems .
Note! All exchange voltages are fully insulated from input AC / DC Voltages and electrical GND. Therefore any mix of external power source and logical signals / relay solenoid control is not properly working .
PC audio via Audio buffer to VA-MC , if audio level is to low.
VA-MC / Stentofon MC-6151 Remote controlled sub-station. Shown here wired to be used in a Vingtor VMP exchange.
VA-365 . VMP - PA interface with basic connection using the versatile Stentofon SAR adapter.
NOTE! DIP switches on the SLB boards normally should be in "OFF" position to avoid "All call / Group call " programming conflicts. Only when using the older non programable "CPB" board these switches should be used.
VA-462 Alarm board + MC 6151 makes an alarmunit to be used in VMP exchanges from Zenitel / Stento / Vingtor Marine
The most important notice!
( These boards must not be "hotplugged" ! )
Like replacing boards in a computer , to avoid serious damage on the exchange electronic boards allways turn off the power before replacing any board in the exchange !!
Most VA boards are obsolete, but still repairable.
VA-111-2 , Fuse board. +24VDC and +5VDC Check soldering.

Stentofon AlphaCom and Vingtor Marine ACM ( Stentofon inside ) , on the station lines , have mixed audio and display data signals . If a PA system is connected , filters have to be used to separate these signals .
FBSAR ( Filter Board Speach Adapter Relay ) is a typical extra function board to adapt a PA system to the AlphaCom / ACM exchange.
SUBCB , subscriber connection board w / RCO connector
