[Milsurplus] LM- Frequency Meter - B and A battery voltages

[Jim Whartenby]

According to the LM-13 manual, 2 each 6 volt batteries in series and 4 each 45 volt batteries also in series.
See: https://bama.edebris.com/download/military/lm13/LM-13.PDF
Seems that all LMs are basically the same according to pages 1 & 2 of above.

Subject: [Milsurplus] LM- Frequency Meter - B and A battery voltages

Been looking in vain for A and B battery voltage information  in "1940"'s

My LM- frequency meter battery connector has 5 connectors 4 look to be 
the same profile and seem to be connected in series, the 5'th connector 
is different seems top be the B battery connection.

were the A batteries 1.5, 3 or 6 volt? for 3 volt 3X4 = 12   if 6 volt;  
6X4 is 24  thinking 1.5V was a bit low since the wire size is not large.

was the B battery voltage:120, 90, 45 or 22.5 volt ?  I'm thinking 90 volt?

If there is a web page that would be sufficient.

Found this :

No average voltages were specified?


Thanks

Hutch
