Anybody have a use for a GE 1358x CRT though, has slight burns on it, from being run at high power as a chart recorder, but otherwise working, complete with the mumetal shielding can. Going to be expensive though to ship, but I can almost guarantee it will survive, will be packed HP style. |

I have a couple of old Russian RF generators, that have some pretty interesting stuff inside, including a bunch of twobs. These are a the G4 series generators, that go from about 1GHz to up to some tens of GHz. The front looks like this: And what's inside, see below. Pretty impressive stuff, especially that mechanical linearity trimming. See this thread for photos of the inside: https://www.eevblog.com/forum/rf-microwave/russian-microwave-signal-generator-g4-80-teardown/ //EDIT: Sorry, I have forgot that I have already uploaded the teardown here ^^ |

Maybe " Display something to make it look technical "? OK, it could be that the bottom line is just "no input", & the juxtaposition of the square wave is just a coincidence. |

Oh, I forgot, I also have an HP TS-510/U UHF signal generator. |
