That's all this was, just a tester for the main event. But after looking at it, having a bit of a play with it and another look, it just seemed a bit too different to waste.
The class 175 is actually a reasonably photogenic creation, certainly when compared to it's peers from the time. Ok, it's never going to win over a Tractor on load 4, but it could be worse. Voyager, Turbostar...

This tube tester is one of the coolest looking emission testers I've ever seen. Most are simple beasts whereas this one has a stylist look to it (I think so anyways). Housed in a nice oak case the tester looks like it has had little use. Currently not working, I'm in need of a schematic to get it going again. If anyone can help, it would be appreciated.

31058 Kawasaki-Hughes OH-6J in TRDI marks. I think this was related to the special bearingless rotor assembly. You can see the elongated pito tube leading from the lower cabin.
A small emission type tester good for antique radio work only. Will test some audio & TV type tubes but go with the 9-66 if that's what you need. Although the case is a bit shabby, the face of this tester is pretty good. It's one of two of these I own and the other is a mess. This one I acquired in a trade, the other I got from ebay. If you're looking for a tube tester, stay away from ebay. It's a place to buy parts units.
A simple emissions tester that came in a kit form assembled by the end user. This one is in great shape and tests tubes as it should.
THIS IS NOT THE TUBE TESTER ON ST LOUIS CRAIGSLIST. THIS TESTER IS LOCATED IN CANADA.
This is a decent emissions tester that commands a good price on ebay. Not worth what they're going for in my opinion but there are a plethora of Heathkit collectors out there that drive the price way up.
This was the first panel I etched. I did not realize I could change the resolution of the image (exported the powerpoint as a picture but with only 72 dpi rather than 300 as I did on the others). It is possible to see the pixels at the edge of the test and border.
oh good lord.
these are so amazing.
they taste like someting right out of a bakery.

This is the early model of the 9-11 tube tester which can be distinguished by the red tube sockets. Later models had gray sockets. A simple emission type tester it will only really tell you if a tube is good or bad, will not match tubes. Line adjust requires a known good tube and voltage adjusted to read between the O's of GOOD. Old enough that they almost always require capacitor and resistor replacement and then calibration to give an accurate reading.
The pull out drawers contained all the parts required to build many projects. I wonder if those capacitors and resistors are still good?
This 9-11 is a later model than the other 9-11 I have posted. It has the black sockets rather than the red. Not really the type of tester you would use for anything other than display purposes. Very simple design that Stark produced for many years. These tube testers are everywhere. If you're looking to buy one, you should be able to find one for $30 or less.
Not as popular as the 9-66, the 8-77 resembles the Hickok 6000 tube tester. Great for antique radio tubes but not so much for the newer tube types. Not as many sockets as the 9-66 or the 12-22A. Decent compact unit. Don't pay too much for one. Save your money for a good 9-66 or 12-22A.
I built this in shop in Junior High School.
Operation:
Put the transistor or SCR in the socket.
Push S2. Note the lights.
Switch S1.
Push S2. Note the lights.
If only the NPN light lit for the whole procedure, you had a good NPN transistor. Same for PNP.
If both lights lit, you had a short.
If no lights lit, you had an open.
I picked this up in Sudbury Ontario and it was full of tubes. The top was long gone but I found the one here at a radio swap meet in Guelph for $5. A good friend was able to reproduce the plastic sign and now it's working great. Great tube storage but takes up a lot of room.

Rebecca Preisler, science undergraduate laboratory intern 2013 from Lewis University, is performing reciprocating tests using steel tribological specimens (cylinders, balls, pins) using a sensitive data acquisition machine. Loads up to 1800 N are possible and continuous measurements are made of vertical force, friction force, specimen position, and temperature. A heater can be used to raise the temperature of the sliding contact to 100 degrees C.

Have you ever wondered how those little, colorful battery tester strips work? They're thermochromic: they change color according to the temperature. When you press the contacts, you complete a circuit, causing a current to flow through the tester. The more energy left in the battery, the bigger the current, the hotter the strip, and the higher the reading.
This comes from our article about how thermochromic materials work.
