[Elecraft] KX3 2m external amplifier

[Mel Farrer]

All of the Mirage amplifiers called linear were just that.  Only special order FM repeater amplifiers could be Class C.

Are those capable of linear operation for SSB as the poster asked? The ones
I had back then were non-linear (class C) strictly for FM/CW only.

Several years ago, we searched for and acquired vintage (30 year old) brick
amps that drive with either 2W or 10W for an output of about 150W. 
They have built-in preamps. These vintage amps were made during the 70s and
80s with the Mirage and RF Concepts name, and were built in Northern
California. They also made versions of these amps that required higher drive
levels -- 30W and 50W, I think, and they also made versions for
440 MHz. I own some of those too, which I use with the FM rig in my shack.
The Mirage name was later bought by MFJ. We found four of these vintage amps
in good condition in a few days simply by asking on two local club
reflectors. I don't remember what we paid, but I do know that we considered
them a bargain. :)

Those older amps are a great fit to an Elecraft rig with an Elecraft
transverter. We use the version that drives with 2W so that we can run the
transverter at the lowest possible power, thus reducing heat.
