See AMS/S18. DD 1968. CANCELLED.
Video Amplifier, lSdB, specifically designed to be
inserted into units in pairs to provide two video paths
from one incoming cable. Similar circuit to AMS/S13.
DD Spec 6.151.
Dual Video Amplifier comprising two AMS/S16 and back-plate
with a single coaxial input, separate mains supplies and
separate outputs for use at receiving sites to enable a
single incoming cable to be split into two separate
DD Spec 6.150.
General Purpose Amplifier superseding AMS/S14. Can be
used with MN6/S02 to increase basic deflection sensitivity
from 100mV/cm to lOmV/cm and provide a differencing
facility and a IM~ input impedance for a probe. Also
provides a calibrated square-wave for probe line-up.
Power required: 7 watts at 240V a.c. CHl/46B, Pegs 25,
