The Pacemaker was meant as a multimode Ranger, but was a short lived disaster. If you are looking for an AM exciter, skip this one!
If you wish to verify my assessment of the Pacemaker, set it to transmit on 21.0 MHz and listen to the awful birdie that comes out along with the desired signal. Rock the VFO back and forth to be sure you are listening to both of the signals. There are lots of decent fun legacy SSB radios to play with that will not get you an OO report or a QSL card from the FCC.
Avoid this one.

Unfortunately the Pacemaker, while made by one of the Best...E.F. Johnson was not their greatest achievement...Though sought after by some collectors, more of a display to collections than a widely used Transmitter.
Whether a transmitter is "a good one to restore" depends on what you want to do with it after it is restored.
The Pacemaker was Viking's first SSB transmitter and has a single 6146 for a final. So the
INPUT power is 90 watts SSB and CW and 35 watts AM.
The output will be maybe 50 watts which is enough to use barefoot or with an amplifier on SSB and CW.
On AM its power is not much particularly with the bands in the shape they are now.
