[R-390] 390() vs 390(A)

[John Lawson]

   I have a nice old girl of a 390 that I purchased about six months ago. 
It needs a good chunk of TLC and some elbow-grease, but it's basically a 
working radio and it's in daily use.

  However, it arrived sans it's rating plate, and I have yet to do more 
with it other than hook it up and listen to it.

   I have most (if not all) of the pertinent docs and manuals, paper and 
CDROM, and this is my 3rd R-390 in the last 30 years.

  My specific question is: is there a quick-and-dirty way to determine if 
one has a 390() or 390(A) from examination alone?  I'm just not up on the 
differences enough to figure this out all by my lonesome.

   I'm just in the last stages of restoring my R-388/51-J [Collins, sn 
258], and when the front panel comes back from Howard Mills I'll turn my 
attentions to the 390.

Cheers and best of the Season!
