[Milsurplus] Working on my ART-13's

[David Stinson]

I've resurrected two ART-13s.
One thing I've found in them and other rigs:  Hi-Z grounds.
The screws that bind everything together get oxides between them 
and the muliti-part chassis.  Get a couple of screwdrivers and 
carefully tweek each and every screw that binds something to ground,
like at the tube sockets and chassis junctions.
A tiny turn or "loosen and re-tighten" is all that was needed.
It will make a difference.
