[Milsurplus] Need coil resistance value of PE-120 vibrators

[WA5CAB at cs.com]

Group,

I have a shunt drive vibrator here that probably (I don't recall for certain) 
on the basis of how the PE-120 it was the spare in was set up I marked 6 Volt 
(VB-12-A).  All original markings on the can are obliterated.  Shunt types 
are hard to test operate on the bench anyway, even if you know what they are, 
and I can't get this one to operate on 6 volts.  If anyone has a known good 
VB-11, 12 or 13 of the shunt type, I'd appreciate it if you would measure the coil 
resistance and let me know what it is.  That would be from pin 8 to pin 7 
(VB-12 6-volt), pin 6 (VB-13 12-volt) or pin 5 (VB-11 24-volt).  If yours doesn't 
have continuity on either of those three pins it is either a Series type or 
has an open coil.  The one I'm trying to ID has a 40 ohm coil.

Officially, the Shunt types should be marked Mallory and the Series types 
Oak, but I have two good Series types here that are only marked Galvin, so so 
much for that clue.

If you have vibrators still in sealed Signal Corps boxes, to save you the 
trouble of opening them to see whether anything else is marked on the vibrator or 
to see from its base whether it is one of these six types (has a 9-pin base 
where the 9th pin is the alignment key and it fits a standard octal tube 
socket), the Signal Corps Stock numbers are 3H6711 (24 volt), 3H6712 (6 volt) and 
3H6713 (12 volt).
