[R-390] R-390 Digest, Vol 79, Issue 24

With CNC and plasma cutting equipment available for adding ventilation holes I 
never really thought to mention them. Obviously they would be required, and I 
rightly assumed everyone in the group was smart enough to realize that. I have 
also used Heathkit cabinets from the Mohawk/Marauder/Apache/DX100B series. They 
look great but take a fair amount of modification to the mounting area, removal 
of spot welds/rear panel, and rear support for the receiver chassis. NO R390 
should hang from its panel. My mention of the Hammond cabinet was merely to 
provide an attractive and economical option to the $350 originals. I currently 
have an SP600 in one of them and it works and looks well. Probably the best area 
to cut vents is on the bottom. A plasma cutter with a carpenters square for a 
guide makes neat undistorted cutouts and barely scorches the paint. 

Most body shops have these, and we have one in our plant for doing window and 
vent cutouts for machines and electrical boxes. Mods that used to be expensive 
and difficult are now easy and affordable. I even made an engraved SX73 panel 
from scratch--a chunk of aluminum and a little programing. I think generating 
the measurements took more time than it did to machine.
Have a great Thanksgiving!

The Hammond P/N for cabinets to fit R-390, R 274, etc is :
RCBS1901017GY2
19" x 10.50 panel, 17" deep
This comes with some blank panels, hardware and is a semi-gloss gray. There are 
other finishes available but this is the one that I would consider the easiest 
to either leave as is  or repaint. I have purchased at least 6 of them for 
various receivers. They look good and are around $160. They can be ordered from 
any Hammond distributor, including Fair Radio I'm sure.

I may be all wrong on this but I think the "real" R-390 cabinet has louvers 
on both sides and on top with screen covered holes in the bottom. All of 
this presumably for ventilation. At least mine does! If you use the Hammond 
unit, I would watch for internal temperature rise!!!

Just a thought! Free and worth every bit!

The R-390 is confusing just like so much of life.

I think that if I took an R-390 and ran it without a cabinet but with the
top and bottom covers in place then I would have similar heating issues
(or worse) than if I ran an R-390 in a Hammond cabinet without but with
the top and bottom covers removed.

As far as I recall, the manual told me to remove the covers if I put the
unit in a rack.  What does it say about installation in the official
government issue cabinet?

Yes, the CY-979A is the cabinet of choice albeit a little hard to find these 
days.  Not sure about the ventiliation in the Hammonds either.

The proper cabinet for an R-390A is a CY-979/URR and it has louvers on the
top and the sides as well as shock absorbing feet. I bought a brand new one
from Frank Krize a number of years ago at Dayton. The radio covers need to
be removed for the receiver to slide into the cabinet. I don't know, and
have wondered myself, if the CY-979/URR is an appropriate cabinet also for
an R-390 or R-391. Any ideas?

I don't know about the R-390 - always rack mounted those we 
had - I had always assumed (there is that dangerous word!) 
that the cabinets would be the same as for the R-391s.

Sherry's R-391 is in (best we can tell) a CY-979/URR...  
which is the single "Mobile table-top"  cabinet called for 
in the manual.  The manual also lists the CY 917/URR for 
"desk-top" use.  Then goes on to also list the CY1119/FRR 
rack (i.e. AN/FRR-39) --  and the CY-1216/U - but I'd always 
thought of those used with the R-388s (i.e. AN/GRC-26).  The 
book says to remove the top and bottom dust covers when in 
the CY-1119/FRR cabinet; but interestingly enough does not 
mention that with the other cabinets (each cabinet has a 
paragraph).  Even so, I'd think it prudent to pull the 
covers - and in the case of the R-390/1 a small fan wouldn't 
be overkill.

best!
