[ARC5] R-26/ARC-5

[Dennis Monticelli]

The small dial mounted to the tube cover underside is indeed for the
remote tuning box.  The presence of the small tuning knob indicates
that this set is of the "lock-tuned" variety.  The local knob was used
by the tech to set the freq on the bench and then returned to its tube
cover mount before the set was re-installed in the aircraft.  You can
tell you have a lock-tuned set if there is a yellow circled S stamped
above the tuning spline.  These sets had superior freq stability.
