www.qsl.net/tentec is Unofficial Ten-Tec web site, showing various models
of gear.
The 425 was first introduced mid-1980's in a darker color to match the
original Corsair. (See qsl.net site for color scheme.)
When the Omni V appeared, they changed the color to the more popular two
tone gray.
Both color schemes were very similar electrically.

Many non Ten-Tec exciter owners complained about the QSK hookup with a
key etc., so they added PTT-QSK/VOX on front panel, and moved the Hi-Lo
voltage to the power supply, which sits on the floor.

Others may be aware of other minor changes not mentioned.
