[R-390] Rack question?

[Dan Arney]

They were designed to be mounted in racks one on top of the other and 
were lined up in some rack after rack. They ran for years like that 
until all of the worry wart hams got to the point of re-engineering them .
Just remove the top and bottom covers and put the sides on and if you 
have one put in a muffin fan at the top to pull some air through them.

Oh yeah the redesign engineers are going to tell you to control the 
voltage. plug them and let them go. One guy that used to be here had one 
in a rack of equipment with unregulated power that had been running 24/7 
for over 5 years with out a failure.

Look at the specs for voltage, very wide SAFE field of operation.

Let all of the re-design guys cause you to get an ugly "ULCER because 
you put 119.965 volts into the radio.

Fill up the rack and go for it.
