[Milsurplus] Receiver wanted (for GO-9) MUCH ADDITIONAL INFO

[COURYHOUSE at aol.com]

Wait...   ok  so the  RU-18 an 19 both  aer   really 14 v  filaments... but 
when used as  a RU-19   resistors  drop the  28  to the 14.   Little  box   
with resistors... did it  get  warm?  Ed#

The RU-18 is a 14 vdc system, while the RU-19 is 28  vdc.  Physically and 
electrically these two systems are identical  (including use of identically 
wired 14 vdc CW-46048D receivers) except for the  dynamotor input voltage, 
junction box power relay coil voltage, and junction  box receiver filament 
voltage dropping resistors for the RU-19.

In the  GO-9, except for two 14 vdc intermediate frequency section and high 
frequency  section antenna switch relays, everything runs off 120 vac, 800 
Hz.   These relay coils are arranged in series for 28 vdc or parallel for 14 
 vdc.
