[R-390] Blue Stripe Box

[Radiograveyard at aol.com]

Hi All; Having owned 134 of these "blue stripes" I can tell you the "box"  on 
the rear is the Navy adaptation for the sets. The connectors are standard  
Navt for all receiver connectins on boats. I just pulled a demilled 390A off a  
scrap ship 6 months ago and the configuration was identical. Many of the blue 
or  yellow or white stripers were depot overhauls most with solid stated power 
 suppilies. The recent one from the scrap boat was a Tobyhanna depot 
overhaul.  Additionally most of the Navy units had the diode outlet pin on the front 
next  to the phone jack.Pete
