[R-390] Hammond Cabinets

[Richard]

I have my Dittmore-Fremuth R-390A in an custom build oak cabinet with 
equipment slides.  There are ventilation slots on the top and bottom 
near the front and a 5" fan with a filter on the rear drawing air into 
the cabinet.  IERC tube shields are on all the tubes.  Airflow is very 
good top and bottom.  Everything runs cool according to my thermistor 
probe.  The fan and filter are Mil-Surplus.  I also added a metal 
bulkhead on the back with pass-through connections for the audio, IF, 
and antenna.   The same done to a Hammond cabinet may not be authentic 
but would still look MIL-SPEC.

These things are getting old and just like me don't like extreme heat 
anymore (I grew up on the edge of the desert in West Texas.)
