[Boatanchors] Another 'what's it?'

[Rod Hogg]

Found another neat item, don’t know what it is.  Maybe some one knows and
may possibly need/want it.

Is a medium size module, looks new, missing tubes -1- 6C4W and a 6AU6W.
Also missing what looks like a test jack, a single wire under neath.

Labeled "MODULATOR HF - A2, P/N 89-322911-2", Got a nice 200/550 X 50-125
ohm transformer on it.  From that I would suspect some sort of mic input,
but maybe just a test equipment modulator??  Has the look of Collins to it.

Any ideas?
