I never had that opportunity, but he's been regarded as one of the "fathers of HF radio equipment" during my lifetime. Of course, so have many others. I know Ulrich Rohde DJ2LR and we had offices only 100' apart or so at RCA-Camden. I worked a bit with Floyd Koontz (WA2WVL) at Harris-RF Communications in Rochester back in the late 70s-early 80s and he was another guru. The best amp guy I've known locally is the one who designed most of the good Henry amplifiers; he's still around and has his own business making really BIG amplifiers, usually starting at 5kW and going upward from there. He'll still make ham amps, but "starting" with 3CX3000A7s and going upscale from that point. An 8877 is a toy. In TX, I did work with a few hams who designed broadcast amps at Continental Electronics (your neighborhood, or at least it was back then), but I was doing power supplies and not RF decks. Their 50kW and up systems were tube-based back in those days (1977-1980 or so) and the power supplies were serious...often 10kV/10A (or 5kV/20A) stuff. That was serious fun.
