Thanks for all the information provided by so many. As Roy Morgan and a
couple others pointed out once I attached pictures of the back of my 390 the
way I  originally received it, I already have what turns out to be a nice
acceptable transformer already which my habit of hanging on to way to much
stuff, I found in a drawer.  It even shows me which contacts it was hooked
up to.  Now all I have to do is wait for my modern ham speaker to arrive and
try hooking it all up.  I was trying to introduce my Grandson to the joys of
the R-390 and Morse Code and it will be easier with a speaker than trying to
share a headphone while actively hunting for one of you ham operators while
on the air.  Harder than it was in Nam searching for VC and NVA signals.
Three years of listening to them, the Chinese and Russian left me hooked for
like listening in to other people.  US Army Security Agency all the way.  IN
GOD WE TRUST, ALL OTHERS WE MONITER. 

Ken
