The point being, there's no such thing as 40 years ago, if GE had any speck of integrity, which they don't, being now only the lowest of bottom dollar whores, thieves & scoundrels in need of the nearest yardarm.
. .where was I?
Oh, yeah, upgrade my boy, always be thinking how to improve the design, esp. when so much money & life is at stake, n'est pas?
Smart folks can reckon how this is cheaper in the long run, short term 'quarter' whores just don't get it.
Thank you. Here’s one good American design in electronics: the first MPPT charge controller for wind turbines. Those of us who are cursed enough with high average winds and willing enough to build small turbines (10-20 ft. rotors) ourselves have been waiting for them for several years.
Let's see, they sold the Mark I about 40 years ago, were up to the Mark III a decade ago and now there are about a dozen new designs waiting for approval.
So if a company sells a product and many years later, someone else misuses it and kills someone, the original manufacturer is responsible?
