    ive picked up a swemar generator
    model lsw-250 made by leader.

    what is it used for, and what does it do?
    has anyone used one.

    thanks

    ** Is that "picked -up" as in "picked up a dose of the flu " ?


    ** TV service - in the days of B&W and valves.


    ** Few valve era TV techs would have even used one.

    Cos most of them were valve jockeys.

    Is that the same kind of thing that Tandy used to have in their Stores,
    (wow, now Iam going back a few years) for testing Valves?

    ** Nope - it is a VHF sweep frequency generator used to help align
    tuners & IF strips of TV sets after repair of same.

    Really a valve era relic, as SS tuners and IF strips rarely is ever needed
    such alignments.

    Do a Google search if you are really curious about them.
