Am working my way forward in a search for a replacement transformer for
my otherwise intact MB-560 transmitter.  The single 6146 is modulated by
a pair of 6AV5's driven by both sides of a 12AT7.

The transformer mounting holes are on center 1.75" x 2.25" the hole in
the chassis is 1.5" x 1.75" and extends .5" below the chassis.  There is
barely 2" from the chassis to the cover (so the transformer may be at
most 2.5" tall).

I believe there may be as much as 600vdc across it (though the rig will
supposedly run on anything from 300-600vdc).

Thanks! & 73, doc kd4e
