Subject: Simple Stuff Forgotten

Gentlemen,

As I am almost the age that can be called "OT" and have found, much to  
my
dismay, that most don't listen to my suggestions I hesitate to suggest
anything that might be considered reasonable (you have no idea how much
abuse I have taken on the subject of software defined radio) but why not
consider what we did 40 or 50 years ago and simply use a Triad N-48X
transformer?   I have one sitting next to me and I know that starting in
1959 I used them in all TUs I built.   All you need is the rectifier and
current adjusting resistor.  I don't think I used a filter capacitor.   
Looks
like Mouser and Allied still sell them.
