[Collins] {Collins} Question on 516-F2 PS

[Garey Barrell]

I don't know that much about the 516F-2, but choke input supplies require a minimum load for 
best regulation.

I suspect that Collins engineers slipped their slide rules and came up with 24k as that minimum 
load.

That said, the original part was +/-5% so 25k is JUST within tolerance!  :-)
