Richard--- WOA!  you mean the  RAK  is not a direct  calibration? I  have 
not studied it  closely  yet.
 
The  RBL had a beauty of a large  dial...  I  fear ours  is not as  nice as 
 yours.. the  dial glass is broken. does  anyone know of a replacement?
 
on  the bad micas  are they really micas or  those  micamold  brand things 
that are really paper inside I have been hearing  about  causing problems?
 
thanks  for the power supply on the  RAK.

The RBL is an excellent receiver, as good as  the RAK, and has the 
advantage of a calibrated dial.  Mine was never in  service, and all the mica 
capacitors were shorted or arcing.  The power  supply is internal .  A good find.

The RAK/RAL power supply has a  design defect in that some voltage dropping 
resistors are nestled underneath a  fiber board with no air circulation, 
and are always shot.  Also they put  too much current through the 884 
regulator as it's only regulating a half-mill  load.  It's easy to make a power 
supply - I've gone both ways, and it may  have been less work to make a new one.

Hello to all!!!  Oh WOW!   this is   good new band!  Can we run RTTY on 
that  band?


OK looked at receivers -   I was wrong  on  the rXX nomenclature on one.... 
We are still happy as they go to 15  KHz
 
#1 - CND-46155 part of rak-7    made  by  RCA  !   Yes! seems to have power 
supply, however,  the cord  is shot. sn 1563
 
#2 RBL-3  sn 363  (weird looks like   flat  national knobs but made by 
Wells Gardner. has  interesting
CHICAGO ILLINOIS  with a decorative thick walled  circle  on the 2 knob 
escutcheon   on top right side knobs.  Neat indeed.
My wild  guess it was  used in  Chicago  Navy radio school maybe touched by 
 hands of Captain   Eddy?  <grin> (would sent pic but do not think the 
reflector likes  it?)
 
#3 some   national  dog house style   power supply  It is not in grabbing 
distance at moment.  perhaps  is for the National knobed  but made by Wells 
Gardner  RBL-3?
 
Sorry  Hue  and  Brian, it was not  that   rare  one ... I had my letters 
mixed.  That one  would have been great to have  too!
 
I like these they were a contribution to the museum  project here.
 
I was looking  for the low  freq  companion  for the RBM HF I have but 
these  are cool... and we always seem to get  things offered from back east  
thus  the RAK shipping would be a  KILLER!
 
This was a drive   down the  street.....
