When ordering new parts, one should always be careful to order the right 
ratings from the catalog. When using surplus/salvage parts, it's always 
best to know the ratings rather than guess at them, and much of today's 
disposable equipment has components with safety margins reduced to the 
absolute minimum to reduce cost and space. When discussing hand-wired 
equipment, however,"Standard" is in the eye and age of the beholder. To 
most of us over 40, 1/2 watt will always be the "standard" we grew up with. 
 From the invention of composition resistors up until the mid-1960s, 1/2 
watt was "standard size" and 1/4 watt was "low power". My grandson plays 
with stuff where 1/10 watt is the norm. He thinks 1/4 watts are big resistors.
