Has any of You out there gained some experiences on actual differences
of the same tube types, but from different manufacturers?
Like f.ex. the 5870 that both ITT and Burroughs has made? ITT says
30,000h for their tubes, when Burroughs says 200,000h.
Thats a huge difference. Are there actual indications that those made
by Burroughs really lasts for over six times longer?
I have a bunch of those Burroughs and ITT tubes, and they are so similar
that I suspect they came out of the same factory in England at the same
time. If not the same factory, at least they were manufactured using
identical equipment.
That style of tube was only manufactured for perhaps 30,000 hours, so
the 200,000 hour lifetime claim is an extrapolation.
You will have to reach your own conclusions.
