[Collins] Mystery Module

[Guido E. Santacana]

Gentlemen,

  I was recently given a Rockwell Collins module that seems to come from
a military set. It contains 4 ceramic tubes that seem to be the finals,
a roller inductor, two more tubes that look like drivers (miniature
types) and gears that seemed to move the roller inductor plus a rotary
switch. I don't have the slightest idea about this module except for the
fact that it probably belongs to some final amp coupled to some
automatic tuner. I can supply images if anyone is interested in
identifying this one.

Many Thanks and Best 73s
