[R-390] New to R390A

[Chuck Rippel]

Welcome to the group.  First, go out and buy that hernia belt you always 
wanted :-)

Actually, you could do a couple of things.  Call Antique Radio Supply 
and get on of their Hammond 600/8-4 ohm audio transformers.  It'll cost 
you about $17.  30-20,000 hz and rated at like 12W.  Its most excellent; 
one of Fred Hammonds personal designs.  While you are at it, buy a half 
dozen .01 and .1 Orangedrop capacitors they sell.  I like the high 
performance versions.  You'll see why in a moment.

You might look around my web page:

Second, when the radio arrives, test it to make sure it works then, take 
the IF deck out and using the capacitors you bought above, swap out the 
ones that just about always go bad.  They are on my web site at:

If you do nothing else, CHANGE C-553, the plate blocking cap for the 
filters.  There is a picture of it on the page noted, above.

Then, sit back and enjoy the radio, learning the technology as you enjoy 
one of the finer things in the hobby.
