[Hallicrafters] tech question please!

Craig,

The May 2002 issue had an article "The St. Louis Switcher", just as you 
describe, by N0XFU.

The Nov/Dec 2004 QEX had a very detailed article about converting an 
"ATX" type computer power supply for ham use. What was quite clear was 
that differnent models had more and more "unneeded" components left out 
- you know; filters, bypass capacitors, etc. <g>

Sounds a lot like the stories of TV set "value engineering" in the 
fifties. Hey if it will work without this resistor, we'll save $.06 per 
set times 200,000 sets - give that engineer with the diagonal cutters an 
award!

So each computer power supply has the potential for uniqueness, even if 
the same part number. One thing you can count on - the fan bearings will 
eventually make noise, even if the RF hash doesn't!

73, Joel, W1ZR
