{Collins} Re: Diode Rectifiers 516F2



The reference of 117/234 VAC was started by some pud at the arrl, who I 
believe found it to be the average based on some data he had collected, so 
to this day, that's what the handbook uses.  These days, most locales have 
much better regulation than in the days of old, so the voltage is stiffer 
and higher.  I really don't believe, and have not ever experienced the 
failure of a BA transformer or cao because of my 125VAC line voltage.  I do 
believe that the dielectric materials deteriorate with age,temp and humidity 
cycling, however. On the issue of SS'ing a HVPS, my general feeling 
is -Don't do it, especially if you are replaceing a high vacuum rectifier 
with a substantial voltage drop.  Gas rectifiers are a different story with 
their low and constany drop, so they are much better candidates for solid 
state replacements.
