  Thanks, I was hoping it was something like that.

> All one piece right?

  Yes, All built in one piece.

   No, this one came from an RCA test facility. I found it in a scrap yard.
 BUT one of the guys there used to work on them in Germany and said that
the US Army used a lot of them there. He's getting old and fogetfull so he
could tell me much else except that most of the problems were bad power
supplies and most of them were caused by bad solder joints. Any chance of
borrowing those manuals?
