[Test-Equipment] General Radio Model 1390-A Random Noise Generator

[J M Noeding]

Hi,

Got the unit at low price since nobody else found it interesting. Seems =
to be for LF since max frequency limit is 5MHz.
Would be interested to learn what it can be used for and possible =
modifications. Is a schematic available? Fortunately it seems to have =
been changed to 230VAC

73,
