philosophy of design. Many
years ago, I remember that Tektronix often designed their scopes to use
tubes from certain
manufacturers, and found that other brands were not suitable. In order to
meet their
specifications, they insisted that certain brands be used in certain
positions. And, if the
tube was replaced, the tube needed to meet design specifications. Was that
good engineering

I have used just about every Chinese tube and of course Cetrons in my
conversions and they all work. Since the Svetlana tubes are a different
design, I
do not use them. I don't think argument holds any water.
