Video Processing Amplifier, used in Decoder
regenerate a standard video signal from a
S.i.S. video input signal. PCB with 33
connector. Indexing positions: 9, 12, 23.
Input Splitting Amplifier used in AM14/s44 on channels in
the frequency range 686MHz-702MHz to control input signal
level and split the feed, giving two separate output
signals to drive AM14/s4s. CH1/66. DD 1972.
AM2 CARRIER AMPL IFIERS
Carrier Amplifier used in PA6/60, PA6/6l as a line sending
amplifier. Redesigned version of AMS/2. PCB in Eddystone
box. DD 1969. DD Spec 2.304. DDHB 2.184. OBSOLESCENT.
Carrier Amplifier used in PA6/60, PA6/6l as a
general-purpose amplifier with 6kO input impedance to
match filters. Updated version of AMS/3. PCB with 15 way
plus. DD 1969. DD Spec 2.304. DDHB 2.184. OBSOLESCENT.
Carrier Amplifier, 30MHz, used to make up loss in
NE4M/501. AM2/ SOlA precedes and AM2/501B follows the
NE4M/sOl. Each has gain of 30dB approximately. PCB in
copper box l14mm x
As AM2/501B but with thermistor to offset variations of
gain with temperature. DD 1966. OBSOLESCENT.
Carrier Amplifier, 21MHz, used to make up loss in a quartz
approximately. l14mm x 90mm x 4smm. DD 1965.
Carrier Amplifier, 21MHz. Broad-band power amplifier used
to drive quartz delay line with a modulated carrier.
Printed circuit board. Used with AM2/502 and mounted with
it in CH1/l2A. DD 1966. OBSOLESCENT.
