[Elecraft] OT: Astron linear PS regulation issues

[Fred Jensen]

I've given up on Astron despite the fact that many people say they never 
have troubles.  Apparently, Astron does not have a supplier for inside 
star washers for screw/bolt connectors, I've found almost crumbly, 
crystallized cold solder joints on the point-to-point wiring terminals 
[in one case, it wasn't soldered at all], and often the case is not 
bonded well [or at all] due to paint and/or no star washers.  These are 
all basic steps in quality electronic construction, there's just no 
excuse for it.
