[R-390] R390A dust covers

[Perry Sandeen]

List,

When I worked at the base receiver site at Karamusel air station in Turkey 1964-1966 all the R390A's we had were IIRC racks of four.

All the dust covers had been removed and in each rack there was a large plate where about a dozen muffin fans were mounted.  We had very few failures as the A/C was set for hanging meat from about 9 PM to 6 AM.

Regards,
