[Boatanchors] UTC VM-4

[Barrie Smith]

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.
