[R-390] Clavier IF Module - Ugh !

Thu, 20 Nov 2003 17:40:39 -0500

The order # on the Clavier IF is DAAB05-70-C-1194
SMC 343621
SN 15

Wow!  Could this be a collectible?

I bought this radio a couple years ago from a guy who said it was EAC, just
now getting around to rejuvinating it.  Everything else appears to be EAC
except for the IF and the Cosmos.  IF works fine now so I guess it doesn't
matter except to the purists.

I'm refurbishing the radio to the point where I want to sell it back into
the "pool".  Replacing the "problem" caps, linearizing the PTO, etc.  I have
two others (a Collins and a Stewart-Warner), which is already one too many.
If anyone is interested in this EAC with a Clavier IF, fixed and working
when I finish going thru it, let me know.  This is not a mechanical rebuild
as Mish or other experts would do, but it will be working well electrically
when I finish, a good starting point to continue from.  The front panel
probably needs a repaint - it's the etched variety.  Knobs and dial cover
probably could use a repainting too.  I'll probably take a loss selling it,
but I need bench space in the garage.
