I went on a road trip with family this last week. We visited my friend
Tom Jennings in LA, who got me started in this whole Nixie tube thing
back in 1999.
He has a display cabinet in his living room with some lovely items. One
is this factory test fixture for the Burroughs beam switching
By noise canceling, my crazy idea was something like this:
Attach a microphone on the transformer, apply a band-width filter at 900Hz,
phase delay 180 degrees and output the amplified out-of-phase signal via a
transducer or speaker mounted on the chassis.
Complete overkill, but could it

Very nice.
Original factory test kit is great. Jan has the original ZM1350 tester at
http://www.die-wuestens.de/dindex.htm?/ZM1350.htm and Ronald has some great
photos of an original Philips factory tube tester at
