[ForSale-Swap] Re: [Milsurplus] octal filament regulators? FS and/or ID

My quick read is this:

115N05 - 115 volt heater element, normally open when not energized 
         and the time delay is 5 seconds.  


6N012Q? D? 0  -  Probably 6NO120, Six volt heater element, normally open with a
              120 second time delay.

115F30 - 115 volt heater element, flasher, 30 flashes per minute (but the
         tolerance might be plus or minus 15 flashes per second).

115MO45 - My guess is 115NO45, again 115 volt heater element, normally open, 45 
          second time delay.


As for the crystal, Gates Radio/Harris used this same style Northern Engineering crystal in their 1960s vintage transmitters, especially the BC-1T.  I suspect their other model transmitters of that vintage also used the same crystal, but I can't verify it for a fact.  I suspect other MW TX manufactuers may have used NE crystals as well.
