    Description

    Atkinson Dynamics AD-27C-4 Series C
    The C denotes a 'MASTER' unit that controls the LISTEN-SEND function of a 'SLAVE' unit.
    The -4 indicates an 'Extreme temperature' unit, 50 F to + 150F.
    Series 3 ( or C) units use a printed circuit board in place of earlier point-to-point wiring.  Is it better ? It is certainly better than the 'B' series which were susceptible to vibration damage due to inadequate support of the output transistor heat sink assembly.  The 'C' series has an additional support bracket for the heat sink.
