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. -- Larry W1HJF (ex K2QDO, ex KN2QDO) email is rapp at lmr dot com |
