I finally got around to posting additional details of the miniature pentode test fixture, including a schematic and list of tubes. Although I built the test fixture primarily to work with 6AU6 tubes the pinout of that tube is so common that just like the dual triode test fixture there is a long list of other tube types that can be tested. There are basically three basing diagrams that can be used with this fixture. Here are the three bas diagrams and the list of tubes that should be supported.
