I would agree with Kieth. Once properly maintained they are an Excellent 
reciever.Manuals can be obtained and repairs though at times difficult 
are not impossible.I have nothing but good things to say about them. I 
own 2 at present and have another 2 across town that I will be 
attempting to rework with aid of a friend.This in no way detracts from 
my overall respect that I have for the R390A which is a superb design.
