| Eppley Laboratory, Newport RI,
standard or Weston cell - one of the wires is broken, so while you may be
able to fix it, I would consider this to be a display piece. A
standard cell is used as a voltage reference for calibration and
measurement

http://en.wikipedia.org/wiki/Weston_cell --- quoted below: The Weston cell, invented by Edward Weston in 1893, is a wet-chemical cell that produces a highly stable voltage suitable as a laboratory standard for calibration of voltmeters. It was adopted as the International Standard for EMF in 1911. Chemistry The anode is an amalgam of cadmium with mercury, the cathode is of pure mercury, the electrolyte is a solution of cadmium sulphate and the depolarizer is a paste of mercurous sulphate. As shown in the illustration, the cell is set up in an H-shaped glass vessel with the cadmium amalgam in one leg and the pure mercury in the other. Electrical connections to the cadmium amalgam and the mercury are made by platinum wires fused through the lower ends of the legs

| I've saved this 5 inch CRT for decades so I could build an
oscilloscope with it, or do something else fun - but I have a scope and
I'm out of space, so this has to go - I can't remember whether I removed
it from a piece of mil surplus equipment, or whether it came separate (in
which case it would be unused) --- I don't see marks from where it would
have been installed, so it very well might be new/unused/surplus NOS or
whatever you want to call it. I'm sure it's OK, I wouldn't
save a bad tube, but I have not powered it up and tested it (to do that,
I'd have to build that scope, right? and then I'd need to keep the scope
and I'd have an even worse space problem than I have now) - so this is AS
IS. It is time to move this from
my collection of really cool and interesting stuff to yours. The
tube is marked "made in Holland" so I presume the real maker is
Phillips.
you can find a data sheet for this tube here: http://www.shinjo.info/frank/sheets/011/d/D13-480GH.pdf Salient characteristics are:

I've sold the Mu-metal shield, so what is left is the tube only, I just haven't taken a new photo. |

| I've had this sitting around for a very long time, never have figured out exactly what it is, time to mystify someone else - it fits into a 9 pin miniature tube base, it weighs about what one would expect for a transformer, on the top it says T200 352534 no other markings anywhere - I don't know how I came to have it, whether it was aerospace surplus or whether it came out of something I took apart in the early 60s - whatever it is, bid on it and make it your problem. It could also be a synchronous vibrator from an instrumentation amplifier but who knows | 2 | ? | 5 ea |  |
