[Elecraft] OT: Audible hum from Astron linear power supply. Fixable?

[Fred Jensen]

Sep "DX Issue" has precious little about DX.

Re Astron:  Many people have very good results with them, there are many 
on mountain tops in the Cactus Intertie system that have run for 
decades.  My experience isn't so good, maybe just bad luck, but I've 
given up on them although I've never noticed an audible hum.  Then 
again, I'm fairly deaf which can sometimes be an asset. :-)

Power supplies are those things that just sit there and hold down the 
desk or floor against gravity outages and I'm looking for reliability. 
My station is currently powered by a Yaesu 1030A that came with the 
FT-847 close to 15 years ago.  It produces 14.3 V all the time, 
regardless of load, and basically, that's all it does [we haven't had a 
gravity outage in that time].
