[R-390] R-390A FS

[Jack/AE7DX]

An addendum to my original post as a result of an inquiry:

I have no idea of the brand...the front name plate is missing and there 
are no other obvious identifiers. The only markings on the receiver are 
rubber stamps, one on the rear, upper right, that looks like a 
spread-eagle with sevreal letters but it is so blurred I can't tell what 
they are. The other stamp is on the right side panel toward the 
front...it is red wit a large letter "A" in the middle and the letters 
"S" to the upper left of the A, the letter "C" to the upper right of the 
A, the letter "L" just abover the cross-bar of the A and four small 
numbers (looks like "9431") below the cross-bar of the A. All this is 
inside a square about 5/8-inch on a side. That's a pretty odd one but 
maybe it will tell a knowledgable R-390A afficianado something. Is there 
some other way I might be able to determine the manufacturer?

FWIW, the front panel is silk-screened rather than etched and is, 
although a bit dirty, is in very nice condition. There alsmot no 
detectable wear on any of the lettering...I note that the "N" in RF-GAIN 
is worn on the uppper right of the letter but I see no other wear on any 
lettering on the front panel.

Also, I forgot to mention that the jumbo "BNC" connector on the rear 
panel has a couple of missing center pins.

Based on previous e-mails with members of this list I think the R-390A 
is likely worth at least $500. Given that I sold the CY-979 case for 
almost that much I figure the receiver must be worth just a little more :>)

Thanks,
