That reminds me of when I purchased my Tektronix 531 'scope a few
years ago, back around 1982. The seller had just "repaired" it, and
somehow had the fillaments connected to the B+ supply. One can
imagine what things looked like when the scope's B+ relay clicked on;
all of the tubes were glowing white for a very brief period of
time---the 'scope was shut off rather quickly. I only had to replace
one or two tubes, from what I recall. Let's see a PC motherboard,
with all of those microscopic components, survive something like that,
and be repaired in a very short period of time! That won't happen;
hence, one could say that older, and well evolved, technology is
superior to newer technology in terms of long-term durability and
repairability.
