[GreenKeys] Atlantic Research Model # DMS-3C-10 Distortion Instrument

[Don Robert House]

James,

Older batteries use a "coded" mating plug so that you could not  
accidentally connect the battery backwards.
Eveready and Energizer both make a NEDA 412 battery that should work  
as long as you get the polarity correct.
I have an old Telco "point meter" that uses a 45 volt battery. I think  
Mouser carries these batteries.
Don't lick the terminals.

Hi Gang,
   I came across an Atlantic Research Model # DMS-3C-10 Distortion
Instrument.   The only thing
I can tell you is it runs off a 22.5 v battery.   Strange thing is it  
has a
THREE prong connector with
three wires.  Does it run off another battery?    I can wire up an  
alternate
power supply.
  Anyone who has the manual I would appreciated a copy.
  I have checked the US Patents and one of the Patents has two battery
voltages on is 22.5, and
the other is  -18 volts.
  Of course the patents listed may not be exactly what is in the  
Distortion
Instrument.
                                                 Any help would be
appreciated,
                                                  James Tanton
