Pretty good receiver Brett. The audio with a good speaker is better
than most Collins I have heard. The rest of the mystic Collins
accolades apply to it. Watch out for bad bypass caps in the front end.
It is a wrist buster, but not as bad as the 390 or 390A.
Have fun and live it up.

I have an R388 on the way.
Should be fun to play with

Most of the changes from the 390 to the 390A, according to Signal Corps
documents, were made as cost-saving measures, not for the sake of improving
