More like the early 70's. I spent from 70, to late 77 keeping one of Nebraska ETV's 3rd of a megawatt transmitters on the air. One of the support engineers brought up a 10 pack of the first HP schottkey diodes up and made the claim that it was a 98% efficient rectifier at 500 mhz. So I removed the twin vacuum tube diode (a 6AL5) that wasn't capable of delivering a volt of video from a monitoring test point into astd 75 ohm load, and soldered one of this new HP diodes in its place. I had to lift it back out of its mount nearly 3/4" just to get it down to one volt. It didn't take me long to modify the other 5. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
