Thanks for rising to the defense of the GPR-90, Glen!  I'll add my 
praise for this receiver, which I use almost every week.  I was 
fortunate enough to get one in virtually mint condition with the 
original speaker, and it sounds every bit as good as it looks (which is 
fantastic).  Mine doesn't drift noticably, on 75 meters where I normally 
use it, tuning is smooth and the receiver just has a high class feel to 
it.  I was able to find the matching GSB-1 sideband adapter which turns 
it into a decent SSB receiver - with hi-fi audio.  My only complaint 
would be the bandwidth is a little broad when QRM is strong, but I 
figure that's what Collins receivers are for ;-)

I paired the GPR-90 up with the B&W 5100B and 51SB-B sideband adapter 
which are contemporaries from the late 50's and I liked the notion of 
the dual external sideband adapters - sort of a transition era thing ;-)
