Hi all sampling gurus, I am continuing performance check of my 7S14 (B020274). Any idea how many pieces were manufactured? All the Hg cells were empty (and were leaked also). I replicated with the con

I have used Tektronix scopes since the 60s. They have always been the gold standard, at least as far as I am concerned. Now my old Tek scopes, I have 4, are getting old and keep requiring service. The
