[R-390] UR 390

[Bob Young]

I am no expert, but if you're asking what is a R-390, it was the predecessor 
to the A and had (I believe someone will correct me and add additional info 
I'm sure) LC filters instead of mechanical filters, also had more tubes and 
supposedly was more complex. I think they had 32 tubes, the A was supposed 
to be a cost reduced version, this topic can get a little controversial 
around here, haha! You will see them on ebay occasionally. I have a 388 on 
the way, my radio after that will be a 390. The way you can tell at a glance 
is that the ant. trimmer is off on the right side I believe and the plate is 
right where you desribed.
