IN-7


IN-7

This type of tube, IN-7, has 2 variants: IN-7B and IN-7A. Anyway, this tube has a set of symbols different from those two. It contains same unit prefix symbols, for example, milli-, kilo-, mega- and same electrical units symbols, for example, ampere, volts and ohm. Also, it has +, – and ~. The dimensions of the tube, however, are the same as IN-4, IN-7B, IN-7A.
