[R-390] Replacement Carrier Level Pot.

Tue, 02 Jul 2002 06:25:24 -1000

Folks:

  A bunch years back I squirreled away a handful of 10 ohm ww pots just for 
this use.  I've used a few and have a very limited quantity left (6) but 
I've decided to dump em and let them get used.  They work perfectly as 
zeroing pots in the R390A.  Once zeroed, my carrier meter stays zeroed.
  These are NOS Clarostat type CM27335 (somebody's part number 140-6109).  
1-1/8 inch diameter x 9/16 inch high, screwdriver adjust shaft 5/16 inch 
beyond the std bushing.  The wiper on these is soldered to the case by the 
mfg which doesn't matter since one end of the original 100 ohm pot is 
grounded.  This ground looks like it can be lifted if it bothers you.  But 
it's worked fine on 3 390As I put them into.
  Will sell to members here for $10 each (includes shipping in US).
