[Hallicrafters] wr600 series vacuum tube info

[Allen Robert Crockett]

Hello.

I've recently dug-up from storage a Hallicrafters SW I acquired when I was
much younger, and I want to start using it again on a more regular basis.
Based on the picture gallery from the website, I believe I have one of the
wr600 series of SWs (mine has a different color scheme than the wr600
pictured at

http://www.w9wze.org/

but otherwise looks very similar).

The radio's circuits haven't been touched for the last 10 years or so,
when my late grandfather tinkered with it for a couple of weeks.  I'm
thinking about replacing some of the old tubes and perhaps see if I can do
any other maintenece, and so I'm curious as to where I can get a copy of
the radio's manual and / or schematics.  I would be grateful for any
suggestions.

thanks!
Allen
