Until the transformers go soft. ;)

S'plane to me how transformers "go soft"??

You've been around as long as I have, don't tell me you've never had a
transformer loosen it's windings, or the varnish disintegrate on the
wire causing transformer noise - both RF and mechanical.

Heck, I've got a Astron RS-30a under my desk that is noiser than hell
and has been since I bought it WAY back when. :)

No flame intended, but I've been involved with electronics since I was
first licensed in 1954 and can count the number of transformers which have
loosened up on the fingers of one hand! Really, Larry's right - the old
analogue chargers were and are far less noisy.
