Hi Sam,

It depends on which one you got. Wawasee Electronics that built those things; marketed different versions of that amp.

The JB2000 10-80 was actually a 10-80 meter amp. Now there was a version of that amp, that was marketed towards the "Export CB" market. What they did was this, instead of the bandswitch, they would toss in a coil that was wound for CB, and add a "Modulator" circuit. Which was also sold as a stand alone, called the JB-12. (There was also a JB-24, which was a 2 tube version, if my memory serves me correctly...) That acted as the driver. Sometimes people would buy the 80-10 amp and do the conversion themselves.  

Anyhow, those beasts were splatter boxes, No filtering, sub-par quality on the parts, and most of the time they were under powered. So, not something I'd run on Ham Radio. 

You might as well have been running a 12 tube D & A Phantom or a one of Abe Brewers's Varmit Boxes. 

Trivia Question, does anyone know what "D & A" stood for and where they were REALLY built? I do. :)

Being in the "Business" of that stuff back years ago, helps. ;0)

You could drive it with low power and it would have a resting carrier of low power (under 100 watts) but when modulated, it would give a peak on a normal what meter over 1000 watts. You could use it key down in the am mode w/0 upgraded transformer because it had not much more of a duty cycle than if in SSB. Sounded really loud on frequency and off.
