The R-390A I used to have and wished I still had was one I got from Fair 
Radio way back when in "used reparable" condition.  It had terrible 
sensitivity.  After some checking and a bit of head scratching, I 
discovered the cam that raise and lower the slug racks were all out of 
alignment.  If memory serves, one sets the radio on 07+000 and the lobes 
on the cams that raise and lower the slug racks should all line up with 
the black lines on the front of the RF deck.  Mine were nowhere near 
close.  When I fixed that problem, she came to life.  What a great old 
receiver.  I need to find another one that the person selling it doesn't 
want an arm and a leg for...

Good luck
