The real problem was the Luxman MB-3045's original design - that the young engineer, Tim, did not run the tubes conservatively to start with.THAT, I know today, is simply NOT good engineering.
Now a days, my " second " audio mentor ( Bob was my first ) has taught me to run tubes at Golden Ratio proportions of their maximum plate dissipations, ( 62% ) and the tubes last, almost " forever" and actually SOUND less stressed also, as a bonus to boot. Live and learn !!
So, as a modern example, my DIY 2015-designed and built Type 45 SET amp dissipates 6.2 Watts from a 10 Watt rated plate. Perfect.
Yes, Robert Fulton was gifted, and a gentleman - a born-again Christian who walked the walk. Robert was 19 years older than I, and like a father-figure to me. I loved him, miss him, but he remains in my heart.
His speakers' 1.6 mHY inductors were called " wroinkers " because they were the coils from Packard cars, starting motors, which were "dumped" by Packard when they went from 6 to 12 Volt systems. The " wroinker " was the sound of the car, when starting with a 6 volt system in the cold Minnesota winter !! :-).
Fun in Minneapolis, at the FMI speaker factory.
BTW, HaHax, we two share a mutual friend, MZ.
