[Amps] Resonant chokes

[Carl]

I have an old GR RLC bridge buried somewhere in the basement; came from the National Radio IRS auction in 91 or so. Havent looked at it since; maybe add to my New Years resolutions....

Ive been to the old and later GR facilities over the years playing chauffer and gopher with test equipment

  Carl asked "How did Henry and others long before them do it before all that fancy stuff 
  became available?"


  General Radio (from your part of the world, Carl) did an inductance bridge where you could superimpose quite large amounts of DC. I have a small Marconi Instruments bridge that has provision for putting DC on electrolytics and inductors - you need an external DC source for that, though.
