I have had very good results with Astron, but I treat their products
like MFJ's: When I get a new one, I always open it up, check that
everything is tight, remove paint if needed, look at the soldering, etc.
It is worth checking the tightness of the connections to the capacitors
every 20 years or so.
The alternative to an Astron linear supply is usually a switcher, and I
try to avoid switchers when possible for reasons of electrical noise and
reliability.

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.

I've found instances of regulation failures caused
by loose hardware. In particular the nuts atop the
filter caps that hold the regulator PC board loosen
and simply tightening then will cure the issue. This
appears to be caused by compression of the PC board
material …"cold flow" to some readers.
There are several other common failures of this series
of PS's, but this one is perhaps the most prevalent.
While you have the cover off, check for paint under the
lug on the green power cord wire …
