It's kind of late now. You should have carefuly rinsed it out at the
time, getting into all the crevices, then let it dry carefully, usually
by putting it in the oven at a very low temperature for some hours.

Every so often the ham magazines would run articles about what to do
with equipment that fell into even salt water. I think Glen Zook did a
piece in CQ in the early seventies, that did deal with something as
complicated as the R390.

I once dragged home a stereo receiver that I found in a bank of snow, it
was suffering from some minor salt damage due to salt used for melting
ice. I rinsed it carefully and then popped it in the oven, and that got
rid of the salt, it ran for years.

I'd like to see the oven an R-390A will fit in...

Run it with filaments only, for a couple days, if you need artificial
heat. Don't turn off "Standby" until you are sure it is dry. Use a dim
bulb tester to prevent damaging current surge. Stay alert.
