> Hello:
>
> Anyone on the list that is familiar with the UTC VM-4 modulation
> transformer?
>
> I just aquired one, and while I was assured that it is perfect condition,
> I'd like to check the windings for continuity, and hipot, as well.
>
> I have a sheet that indicates various hookups for different impedences,
> but it's not all that legible.
>
> What I'd like to do is run a continuity check on the full windings, at
> least to start with.
>
> I wish I had a schematic of the windings.
>
> Any help appreciated.
