The R390 has two RF tubes. The front end of a R390 is a 6AJ5 type tube.
6AJ5's are also used in the first and second oscillator of the R390. The R390/A
uses 5654/6AK5's for the first and second oscillator. I do not have a 6AJ6 in my
tube manuals so you might e-mail to see if that’s a typo for the 6AK6's Try
antique radio tubes if you need tubes. You likely do not need a whole set of
tubes Shop around for your tubes. Prices are all over the place and you can pay
way too much.

Their web site is: http://www.pomonaelectronics.com
The "Contact US" link asks you to register to get information. But give it a try.
They don't list them in the search for products listings, but there MIGHT be
some on the shelf. You'll need to sit down when you find out the price, though.

I get all my tubes from Roger KE7NTD including the 3TF7. His Tube
business web site is http://www.vacuumtubes.biz/index.html He is very
reasonable on prices and a great guy! Having said that, I converted my
R-390A to eliminate it. There is lots of info on how to do that.
