[Boatanchors] Need Globe King 500C Modulator Question

[Dennis DuVall]

In the T-368 (Military) the spark gap is on the secondary side of the mod transformer.  No gaps on the primary.  Anyone have any data on T-368 mod transformer failure rates/modes etc?

The gaps should be wired across the primary, using two gaps, one from each end of the winding to mid-tap, not just one gap across the entire winding.  No gap should be placed across the secondary.
