<div class=""><font size="2" face="Arial" class=""><span class="718542119-30032016">I thought that many
of you would find this article to be interesting. It shows a 1961
advertisement (in Scientific American) from GE Receiving Tube Division,
encouraging consumers to favor electronic computers that were designed around
tubes rather than high-cost, widely-variant solid-state
devices.</span></font></div>

<div class=""><font size="2" face="Arial" class=""><span class="718542119-30032016">Quote:
"Electron-tube equipment offers you even more significant savings from simpler
circuitry, proven design, highest overload protection and uniform operating
characteristics over a wide range of temperatures." </span></font><font size="2" face="Arial" class=""><span class="718542119-30032016">Of course, today one could add
"EMP-resistance" among the features of a tube-based
design...</span></font></div>

<div class=""><span class="718542119-30032016"><font size="2" face="Arial" class="">I've still got quite
the collection of electron tubes, some with "tested good" stickers dated
1928, and some looking like a mogul light bulb with an anode cap (high-current
rectifiers for sound systems), plus a couple of tube-testers. Maybe
I could design something that utilizes all of those tubes, although perhaps
I should wait until next winter when I need the heat...</font></span></div>
