Check those pictures out. They are the best description. This is one of the earliest tube tester you will find. It will test those very earily tubes. It will not test the later tubes like 12ax7s. This may be the first tester to test the MU of a tube. It does this by testing the current draw of the tube and then when you push the bias button it shows the change in current. I have encluded the tube list it test and a schematic. I have not tested it for accuracy so it is sold as it. Also note someone has added and extra tube socket on it. Ask if you have any questions. Als note it has the pin sockets at the top to test the overhead filament tubes like McCullough and Kellogg tubes. It does not however have the set up (or wires to connect the tube) listed for these tubes. So to test the 401 tubes set it with 3 volts filament and the rest set up as a number 12a tube.
