Dan,

I sounds like Tom said Jerry said, the whole world knows you need some
6AK5 / 5749 in your R390. Not something you have to do, but you will likely 
hear more with some 6AK5. 

Now your looking for tubes, The first thing there is all brands are not equal.
Take what you can get today and try them. Do not pass up any swap meet 
bargains and take those home. Try them. Swapping tubes is the difference between 
very good receivers and really awesome receivers (my to cents) A tube will not 
fix a problem that is not the tube. But once you get all the problems fixed, 
then tubes do make a difference.

You may yet need to pull the RF deck to change some caps. Do some more 
reading and lets see if we can get you the whole list of things to check for before 
we send you off to just yank the RF deck for fishing venture. There are lots 
of other specific not invasive test that can be conducted before we send you 
down that path.

If you were a student in the 33 or 31 MOS an instructor would not hesitate to 
make you pull that deck on the drop of a cigarette butt. However you would 
also have been trained and psychologically conditioned to do the task prior to 
jumping in. For 33's that instructor was a hell of a lot more scary than any 
piece of hardware.
