[Milsurplus] [ARC5] WTB Original LM-10 manual

[Robert Downs]

To the best of my knowledge (or maybe better AFAIK), there were only two different power supplies ever made for the LM family.  The NT-20104 has an AC voltmeter on the front panel.  And the NT-20104A or sometimes NT-20104-A has a red pilot lamp.  Otherwise, they are all the same after taking into account the fact that several different contractors made them and may have used slightly different component shapes internally.  But all are functionally interchangeable.

On a source of black rubber jacketed cable in various OD's and wire gauges, go to McMaster.  I think that they call it control cable or something similar.  It is sold by the foot.

I have unearthed a power supply for the LM-7. Not sure what it's type number is. My years-old taped on note says "Needs Work" so I may be looking for info on the thing. 

I do have a set of the connectors (bought in 2014), but no rubber-jacket cable of the right diameter to fit the connector compression clamps. I may make two cables from the one plenty-long original cable here in use on the LM-20/CBLC-20104-A. 

This LM-20 is just older than I am (77) and works puuurfectly!
